In trying to build faster computers for the future, some researchers are looking to the speed of light. A team of engineers have built a small, simple circuit with five lasers, Chemical & Engineering News reported. It’s a step toward computers that would perform calculations based on the movement of light, instead of electrons in a silicon chip.

Light-based computers would be more energy efficient and at least 1,000 times faster than computers today, according to C&EN. Because of the physical properties of light, however, the laser circuits researchers have made are too large for today’s devices. Now, a team of scientists in Berkeley, Calif., has found a way to make smaller circuits by making light travel not as the usual photons, but as plasmons.

In the new circuit, light from a laser travels along the surface of a material in waves. The plasmons created by this process are able to travel in a narrower beam without losing their strength, as would photons, the usual particle of light.

The Berkeley scientists also built the circuit so that they are able to control how intense the plasmon beam is. Two different intensities of beams could be used to represent the 0s and 1s of binary computing, C&EN reported.

This is the first time anyone has been able to control the intensity of a plasmon beam, Chih-Kang Shih, a physicist at the University of Texas at Austin who was not involved in the Berkeley research, told C&EN. Next, the plasmon team should ensure they are able to switch intensities quickly and make an even smaller circuit, Shih said.

The Berkeley-based scientists, including materials scientists from the University of California, Berkeley, and the Lawrence Berkeley National Laboratory, published a paper about their work Sept. 18 in the journal Nano Letters

  1. Wonderful blog! I found it while surfing around on Yahoo News.
    Do you have any suggestions on how to get listed in
    Yahoo News? I’ve been trying for a while but I never seem to get there! Thanks

  2. Highly energetic blog, I loved that bit. Will there be a part
    2?

  3. Pretty nice post. I just stumbled upon your
    blog and wished to say that I have truly enjoyed browsing your blog posts.

  4. I couldn’t resist commenting. Perfectly written!

  5. Very nice article, exactly what I wanted to find.

  6. Woah! I’m really loving the template/theme of this blog. It’s simple, yet effective.

    A lot of times it’s very hard to get that “perfect balance” between user friendliness and appearance. I must say you’ve done a superb job with
    this. In addition, the blog loads very fast for me on Internet explorer.

    Outstanding Blog!

  7. This blog was… how do I say it? Relevant!! Finally I’ve found something which helped me. Thanks!

  8. I know this site offers quality based content and other stuff,
    is there any other site which provides such stuff in quality?

  9. Hey very nice blog!

  10. This design is incredible! You certainly know how to keep a reader amused.
    Between your wit and your videos, I was almost moved to start my own blog (well, almost.
    ..HaHa!) Fantastic job. I really enjoyed what you had to say, and more than that,
    how you presented it. Too cool!
