Paper Abstract

A monolithically integrated planar dual InGaAs pin photodiode with a 3 dB bandwidth of 18 GHz has been fabricated for balanced optical coherent receiver application. The photodiodes are designed for front and backside butt-jointed fiber coupling. They exhibit a very low dark current of 10 pA at -10V, a capacitance of 85 fF and a responsivity of 1 A/W. After 4500 h operation no chip failure has occurred. High impedance front-end modules have been assembled with a 3 dB bandwidth of 8.9 GHz and a coupling efficiency of more than 90 percent (-0.5 dB).
