Experimental results of a photonic downconverting W-band receiver are presented, showing a low-ripple unamplified conversion gain of −21.2 dB from 75–110 GHz. Additionally, 1 Gb/s wireless data transmission at 90 GHz is demonstrated.
40 GHz quantum-dot mode-locked lasers providing low-jitter optical and electrical microwave signals are investigated. 160 Gb/s data transmission based on differential quadrature phase-shift keying and optical time-division multiplexing is demonstrated using a packaged module.
Over the past decade, different widely tunable lasers and transmitter PICs have been conceived and developed. In this paper, we will review the state-of-the-art in this arena, and discuss recent results, including widely tunable lasers in different wavelength bands, and compact integrated optical transmitters.
We present a CMOS integrated optical receiver having under-damped transimpedance amplifier (TIA) and CMOS avalanche photodetector (APD) realized in 65-nm CMOS technology. The under-damped TIA compensates the bandwidth limitation of CMOS APD and provides enhanced receiver bandwidth performance with reduced power consumption and better sensitivity compared to previously reported techniques. We successfully...
