Evanescent Lasers to Speed Up Data Transmission

samzenpus posted more than 6 years ago | from the greased-lightning dept.

Technology 82

Roland Piquepaille writes "Researchers at UC Santa Barbara (UCSB) have built the world's first mode-locked silicon evanescent laser. But what is an 'evanescent' laser? It is a step toward 'combining lasers and other key optical components with the existing electronic capabilities in silicon.' In other words, this research work will provide a way to integrate optical and electronic functions on a single chip. As these evanescent lasers can produce stable short pulses of laser light, they will be useful for many optical applications, such as high-speed data transmission or highly accurate optical clocks."

I BELIEVE! (-1, Offtopic)

Anonymous Coward | more than 6 years ago | (#20326163)

Heck, laugh if you want. Maybe I'm too much of a kid. Maybe I'm young at heart. Maybe I'm just a little superstitious.

But every now and then, right around dusk, I'll look out my back window as the sun falls slowly to sleep. And I'll chuckle a little when I catch myself. I just can't stop believing that Negroes exist!

I never doubted the existence of Negroes as a kid. My parents smiled knowingly and said nothing. But at night, lying in bed, I could imagine that Negroes really might be chirping and fluttering across the nearby countryside, scouring the foliage for the secret ingredients of Negro Stew.And of course I believed the legend that a young child, pure of heart, could make a Negro appear. If I was a good boy, perhaps I might see one tip his top hat and give me a wink!

It was Mark Twain's classic novel on Negro life, Yassuh, Massuh Clements, Whatevuh Yuh Say, Suh, that hatched an ill plan of mine to actually see a Negro in person. In that immortal piece of Americana, Twain recounts the old legend that a young lad can summon a Negro. He must stand outside at dusk, face southeast, hold a tooth that has just fallen out, and sing:

Cah Loo, Cah Lee, Tra Loo, Tra Ley,
A Negro song today!
Come hear my call, come one and all,
Tra Lee La Negro, hey!

If ye be keen to come along
And sing the magic Negro songs,
Then Tra Lee La, Tra True La Ley,
T'will be a Negro day!

If all goes well, the young boy will hear a voice singing in the distance:

A taste of stew, and Negro Pie,
Oh who will break my fast with me?
For me it is a weary life,
But I will sup with thee.

For tales, I'll tell you of a lass,
My Negress love at distant shore.
We'll sing beneath an apple tree,
A merry Negroling and thee,
Until the dawn is born.

And, after suddenly appearing with a flash of light and burst of smoke, the Negro will exchange the tooth for a bag of silver dimes.
Well, when I was seven, I was ready to try it out. Sneaking out of my bedroom, I crept down the stairs and into the backyard. I was certain that I would actually see a Negro! What would he be like? Would he be mean or friendly? Would he show me the magic sword used to fend off the Irish?

After singing into the night as loudly as I dared, I stood with an expectant grin. The grass was soft under my pyjama feet. There seemed to be a sparkle in the air! But after several hours of waiting, I slumped with disappointment. No Negroes for me. My father rushed downstairs upon hearing me come in. At first he was worried, but his concerned frown turned into a gentle smile when he heard what I had been up to.
"Son," he said, somberly. "There are no such things as Negroes."

A little bit of my childhood died that day. But not completely. Whenever the dusk falls on a clear summer day, I look out to the southeast and dream of a bite of Negro Pie.

Okay, probably not (yet). But I'm actually serious about that. Aside from the awesomeness that would be seeing tux on the boot screen of a photonic device, there's the sheer awesomeness that is just running a computer on (mostly) lasers instead of electricity. Even if it's still a long ways off.

And lets not forget how much power it could theoretically save, what with not having to deal with resistance (not that light doesn't have its own problems, ie refraction and diffraction, both big deals when working on small scales).

bariswheel (854806) | more than 6 years ago | (#20327425)

So, to straighten some of the anonymous cowards out a bit.

UCSB is labeled a party school mainly due to the insane town next door that is Isla Vista, of which the majority of the population are actually community college students in the city, but prefer to live by the beach, hence they live right next to the uni. This misrepresents the university and continues to degrade its reputation. Yes, I am an alumni, and yes, you've struck a small chord on the proverbial nerve, but it's ok.

The university has produced more nobel laureates than any university in the last 7 years. UCSB is what Berkeley was 30 years ago, but reputation takes a while to build, so in 20 years or so, you'll be hearing about UCSB the way you hear about Berkeley, UCLA, etc..

The University's materials science program, I believe is the best in the world; and its Particle Physics (Kavli Institute of Theoretical Physics) is worldly renowned. Stephen Hawking makes regular visits, and I've had the honor and privilege to meet him here.

UCSB also harbors a nanofabrication cleanroom facility, at the Kavli Institute of Nanoscience. Before I left the area more than a year ago, the research going on at the Kavli Institute as well as these cleanroom facilities was disturbingly fascinating, you can find out more info if you wish.

A lot of Googlers are also from UC Santa Barbara, including the Senior VP of Operations, Urs Hoelzle, who taught CS at the College of Engineering.

I attended UCSB for a while as well, but did not get a degree there. I went somewhere else.

I would say that the majority of wild Isla Vista residents are in fact UCSB students. There are many Santa Barbara City College students there, but all the people in my apt building were UCSB. Also, there are a lot of Mexican laborers in the town.

The Engineering and Materials science departments are outstanding. But it is a large university and there is a lot of party people. It is a fact. UCSB has the largest percentage of white students in the UC system. That is also a fact.

The ECE department is universally regarded as excellent and myopic... all they care about is compound semiconductors. We can thank Nobel Laureate Herbert Kroemer for that.

I agree with you that UCSB is a wonderful school. But the fact is there are a lot of 24 hour party people as undergraduates. Denying that does not improve the reputation of the science there.

Ungrounded Lightning (62228) | more than 6 years ago | (#20334975)

I was wondering what this "evanescent laser" bit was about. That article clarifies it.

Light confined to a waveguide by total internal reflection actually penetrates about a third of a wavelength into the space around it. (Essentially "sampling" the space to "find out" that the refractive index is too low for it to fly away. B-) ) A number of things can be done with this effect (such as measuring the refractive index of opaque substances like ketchup).

In this case what they've done is build an optic waveguide in silicion (by etching it and perhaps then oxidizing it into glass) and bonded to it an LED with the active region over the waveguide.

  - The evanescent wave penetrates into the region where the diode amplifies light, which provides the gain, pumping up the light in the waveguide.
  - The waveguide provides the resonant cavity for the laser, as well as all the optical plumbing.
  - The waveguide (and all associated optical plumbing) can be easily and accurately constructed using integrated circuit etching techniques.
  - There is no critical alignment between the diode and the waveguide. Just get it within a range of positions that put an active region on top of the waveguide for about the correct length in the correct segment.

It's not really a silicon laser (4, Insightful)

Hal-9001 (43188) | more than 6 years ago | (#20327337)

According to TFA, the stimulated emission of light actually takes place in an indium phosphide (InP) laser diode. The laser diode is bonded to a silicon waveguide, which acts like a miniature optical fiber to guide the laser light around the chip. The "evanescence" is because the laser light is evanescently coupled from the laser diode into the waveguide. A proper description of evanescent coupling requires a pretty sophisticated understanding of electromagnetism, but the short version is that if you shine a laser beam parallel and adjacent (within a few microns) of a waveguide or optical fiber, some of the laser light will hop over and start propagating down the waveguide or fiber. In particular, by placing the actual laser parallel to and near a carefully-designed waveguide, you can have almost all of the laser light emitted into the waveguide, even though the constituent atoms of the waveguide are not emitting any light at all! For this reason, I think the name "silicon evanescent laser" is misleading since the silicon isn't emitting any light, and Roland Piquepaille's description of evanescent lasers is just flat out wrong. Getting silicon to emit light remains an extremely difficult task, and as far I know, no one has succeeded yet in getting silicon to convert electricity directly into laser light.

If anyone wants to read the Optics Express paper referenced in TFA, it's available online at http://www.opticsexpress.org/abstract.cfm?id=14097 3 [opticsexpress.org] . However, that paper doesn't really define the term "evanescent laser" anywhere, so I had to go back to one of the research group's earlier papers [opticsexpress.org] to find a decent description of an evanescent laser and understand the physics of the device.

You mean to say that Ramen lasers don't work by converting a powder and a dried noodle cake into a delicious snack, which then powers a geek who invents frikkin' lasers?

Until we decide to just get it over with and switch to a direct-bandgap semiconductor. Probably as soon as they figure out how to make a decent P-type fet on GaAs...

Agreed that would be a solution, but the point is that the infrastructure for silicon processing is already there. When you have to switch to GaAs products, you have to change all of the cleanrooms and equipment used to make the products. This is currently seen as being a much more expensive solution. What we're trying to show is that you can do optoelectronic functions using this hybrid platform just as well as (or at least almost as well as) you could on pure GaAs or InP, but now you can integrate that on the same chip as all of the inexpensive silicon electronics (and passive optics). Additionally, we're learning that there may even be some other advantages to this hybrid platform aside from just being a cheaper solution.

I'm picturing Amy Lee [wikipedia.org] with a frickin' laser on her forehead.

They gave Amy Lee a laser? (1)

Yes, of course... to vaporize (or rather, to evanesce [wordreference.com] ) any remaining band members [evboard.com]

Everybody keeps reading the word Evanescent as something else. Hopefully this tech will be used to make better contact lenses.

Anyone can stick monitors together with black seams between. This display is useless. There are companies out there doing this with seamless blending between projectors etc. UCSD should be embarrassed by this and the claims made.

it's still no match for a good blaster at your side, kid.
