#OPTICAL: "CMOS optical pulse compressor debuts"

In the future, all CMOS chips will communicate by modulating beams of light that silicon waveguides are routing around, between and among semiconductor chips and the systems using them. The pulse compressor demonstrated here is one more component for future engineers to use when designing CMOS optical interconnects. R. Colin Johnson, Kyoto Prize Fellow @NextGenLog

Here is what my story in EETimes says about MEMS resonators: Silicon photonic pulse compressors were demonstrated on CMOS chips recently by researchers at the University of California at San Diego (UCSD). 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...
