The fabrication and characterization of p-i-n photodiodes integrated with wide spectrum focusing reflectors using nonperiodic strip and concentric-circular subwavelength gratings are presented. The experimental result...
The Gaussian doping is used to optimize the performance of InP/InGaAs uni-traveling-carrier photodi ode (UTC-PD) in this letter. The UTC-PD structure is modeled with drift-diffusion approach and the comparisons of t...
