The results indicate that tolerance of the optical coupler splitting ratio is equal to or less than ±6% for the DFG-OPC.We present the design of an adiabatic taper coupled Ge1-xSix electro-absorption modulator, which is based on Franz-Keldysh effect. The device has an active region of 0.8×50 µm2, an extinction ratio of more than 6 dB and an insertion loss less than 3 dB at the wavelength of 1550 nm. The operating bandwidth can be broadened to more than 90 nm by an AlN block assisted heater with only 6.2 mW energy consumptio
