摘要

We design and fabricate a parallel system with 10 high speed side-illuminated evanescently coupled waveguide photodetectors (ECPDs). The 10 ECPDs exhibit a uniform 3 dB bandwidth of 20 GHz and low dark current of about 1 nA at 2V reverse bias. The 10 ECPDs also exhibit uniform photo-responsivity of about 0.23A/W with an active region of 5 x 25 mu m(2). The photodetector array has a total bandwidth of more than 200 GHz and can be integrated with other optoelectronic devices.
