Integrated Uni-Traveling-Carrier Photodiodes with High Responsivity and Wide Bandwidth for Microwave Photonics

Back-to-back integrated uni-traveling-carrier photodiodes with high responsivity of 0.83 A/W and wide electric bandwidth over 40 GHz are realized. Resonant cavity-enhanced uni-travelling-carrier photodiodes are optimized for high responsivity and wide optical bandwidth over 20 nm.
