We demonstrate monolithically integrated n-GaAs/p-Si depletion-type optical phase shifters fabricated on a 300 mm wafer-scale Si photonics platform.We measured the phase shifter performance using Mach–Zehnder modulators with the GaAs/Si optical phase shifters in both arms.A modulation efficiency of V_(π)L as low as 0.3 V·cm has been achieved,which is much lower compared to a carrier-depletion type Si optical phase shifter with pn junction.While propagation loss is relatively high at.5 d B∕mm,the modulator length can be reduced by the factor of.2 for the same optical modulation amplitude of a Si reference Mach–Zehnder modulator,owing to the high modulation efficiency of the shifters. 展开更多

We propose and experimentally demonstrate capacitive actuation of a graphene–silicon micro-ring add/drop filter. The mechanism is based on a silicon–SiO_2–graphene capacitor on top of the ring waveguide. We show the capacitive actuation of the add/drop functionality by a voltage-driven change of the graphene optical absorption. The proposed capacitive solution overcomes the need for continuous heating to keep tuned the filter's in/out resonance and therefore eliminates "in operation" energy consumption. 展开更多
