We demonstrate a transmitter and receiver in silicon photonics platform for O-band optical communication that monolithically incorporates modulator driver, traveling-wave Mach-Zehnder modulator, control circuitry, photodetector, transimpedance amplifier (TIA) the GlobalFoundries Fotonix (45SPCLO) platform. The show an open 112 Gbps PAM4 eye at 4.3 pJ/bit energy efficiency, not including laser. Extensive use of gain-peaking enables our driver TIA to achieve high bandwidths needed 45 nm CMOS-silicon process. Our results suggest alternative frequent approach bump-bonding BiCMOS drivers TIAs photonics.

III−V Compound Semiconductor Nanopillars Monolithically Integrated to Silicon Photonics
We propose a platform based on III−V compound semiconductor nanopillars monolithically integrated with silicon photonics. Nanopillars were grown in a process free of metal catalysts onto silicon at low temperature, and a bottom-up process was applied to define the photonic integrated circuit. Stimulated and spontaneous emissions from the nanopillars are direct coupled to silicon waveguides.

We present a 12.5-Gb/s monolithically integrated optical receiver with CMOS avalanche photodetector (CMOS-APD) realized in 65-nm CMOS technology. The optical detection bandwidth limitation of CMOS-APD due to the carrier transit time is compensated by underdamped TIA. With this optical receiver, 12.5-Gb/s 850-nm optical data are successfully detected with bit-error rate less than 10 at the incid...
