Abstract :
A uni-traveling carrier waveguide integrated photodiode (UTC-WIP) combining the advantages of a coupled waveguide integrated photodiode (WIP) and a uni-traveling carrier photodiode (UTC-PD) is investigated. Preliminary measurement results show that the DC responsivity is 0.4 A/W without an anti-reflection coating, and the peak pulse response can reach 94 mA (4.7 V across a 50 /spl Omega/ load) when the bias voltage is -9 V. The resulting device is capable of operating at 20 GHz. The IP/sub 3/ at 1 GHz and 18 GHz are 24 dBm and 8 dBm, respectively.
