Abstract :
In this paper, simulations are conducted to investigate high speed uni-traveling-carrier photodiodes (UTC-PDs). The Gaussian doping profile, which can introduce potential gradient and electric field, is presented to be used in the absorption layer. Compared to constant doping and step-graded doping, bandwidth of UTC-PD with Gaussian doping is improved substantially.
