UCSD demos silicon photonic pulse compressors on CMOS

Keywords:CMOS? silicon photonic pulse compressor?

Researchers at the University of California at San Diego (UCSD) demonstrated silicon photonic pulse compressors were demonstrated on CMOS chips recently.

To be used for optical time division multiplexing (OTDM) in future on-chip silicon photonics, the pulse compressor design used a dispersive optical grating to generate short, powerful communications pulses on a CMOS chip.

UCSD claimed its pulse compressor is the first CMOS implementation strong enough for OTDM.

Future CMOS chips will communicate over optical interconnects, using pulse compressors and other on-chip photonic components to aggregate individual data channels into high-speed optical signals. Besides speeding up the interconnect over copper wires, optical signals also reduce power consumption and run cooler than electrical signals. The compressed pulses aggregated by UCSD's device were seven-times shorter than the pulses in the original signals.
