摘要：
Photodiode (PD) is a key component in optical transmission and optical measurement systems. In this paper, we present the design and fabrication of traveling-wave edge-coupled Unitraveling Carrier (UTC) PD. The fabricated UTC PD with 40 mu mx5 mu m waveguide shows 3dB bandwidth 13GHZ and 32GHz under 0 biases and -1V respectively. In parallel, PIN PD was also fabricated for comparison and only shows 4GHz and 18GHz under same bias conditions. This indicates the UTC PD is superior to the PIN PD for higher speed operation, especially in application of system without power supply.
