The. photodiode (PD) is a key component in optical transmission and optical measurement systems. In this paper, we present an InP-based InGaAs Uni-traveling Carrier (UTC) PD designed and fabricated for high speed and high power applications. A UTC PD with a 40micrometer waveguide shows a 3dB bandwidth up to 40GHz and photocurrents of up to 10mA without saturation in our measurement range.
