We've had light-emitting diodes and lasers for more than 40 years, transistors for almost 60. But until now, we haven't had a single device that can take an electrical input and simultaneously output both an electrical signal and an optical signal. ......
Now, based on our recent work at the University of Illinois, there is such a dual-output device, and a sound reason to envision a future where high-speed computing meets the next generation of broadband communications.
The ability to send and receive signals at the equivalent of three DVDs worth of data—100 billion bits—per second could turn those herky-jerky teleconferences between offices in Tokyo and New York City into high-resolution events. Grandparents in Montreal could watch a granddaughter in a school play in St. Louis through a video cellphone. Supercomputer grids crunching the test data from the world's most advanced particle accelerators might produce results in minutes instead of days. And if you think Internet searching is fast now, wait until servers with transistor-laser-equipped microprocessors pluck answers to the most obscure queries from the hundreds of billions of video, audio, and text files expected to be available online in the next few years.
