Low bias, low dark current photodetection in silicon MZM embedded with vertical PN junction
conference on lasers and electro optics, pp. 1-2, 2017.
We demonstrate an all-silicon photodetection inside a modulator. Due to the high electrical field in the vertical PN junction, a relatively high responsivity of 21.5 mA/W is observed at the low bias of −7 V and low dark current of 16 nA.
