Abstract

Localized GOI wires have been grown using a LPE process resulting in single crystal layers up to 400 µm in length and 5 µm in width. We have reported on the design, fabrication and characterisation of a 4-channel AMMI structure integrated with germanium p-i-n photodetectors to form a silicon photonics receiver. Light detection at 50 Gb/s has been demonstrated with a low dark current of < 20 nA at -1 V bias. The AMMI structure exhibits a low insertion loss of < -0.5 dB and cross-talk of < -15 dB across the 4 channels.
