Design of high bandwidth efficiency product gradual doped partially depleted absorber photodetector with spacer layer
Asia Communications and Photonics Conference 2021（2021）
摘要
A partially depleted absorber photodetector with spacer layer is presented, which adopts Gaussian profile doping. The bandwidth is 59.8GHz and the quantum efficiency is 60.4%. The bandwidth efficiency product is 36.11GHz which is 49.7% higher than conventional partially depleted absorber photodetector under the same active area and bias voltage.
