10Gbit/s all-optical NRZ-OOK to RZ-OOK format conversion in an ultra-small III-V-on-silicon microdisk fabricated in a CMOS pilot line

Abstract

Abstract:We report the demonstration of an all-optical, bias free and errorfree (bit-error-rate ~10 -12 ), 10Gbit/s non-return-to-zero (NRZ) to return-tozero (RZ) data format conversion using a 7.5µm diameter III-V-on-silicon microdisk resonator. The device is completely processed in a 200mm CMOS pilot line. The data format conversion is based on the phenomenon of pulse carving of an NRZ optical data stream by an optical clock. The underlying physical effect for the pulse carving is the change in the refractive index caused by the generation of free-carriers in a pump -probe configuration. We believe it to be the first NRZ-to-RZ format convertor built on a hybrid III-V-on-silicon technology platform. References and links 1.D. Norte, E. Park, and A. E.

Phase-Preserving Power Limiting Function Using InP on SoI Photonic Crystal Nanocavity

“…For future photonic circuits, InP over silicon-on-insulator (SOI) hybrid technology is an extremely promising solution as it combines CMOS compatibility with the optoelectronic properties of III-V materials. The III-V/SOI hybrid technology has recently allowed the demonstration of lasers [1], amplifiers [2], modulators, flip-flops [3], wavelength converters [4], modulation format converters [5] and 2R-regenerators, including power-limiters [6].…”
