germanium photodetector (Ge PD) with lumped structure based on related parallel Ge …

Saturation current-bandwidth product (SCBP), the key of figure of merit in high-speed and
high-power photodiodes (PDs), is mainly limited by the tradeoff between carrier drift time in …

Four-element modified uni-traveling-carrier (MUTC) photodiode arrays (PDA) flip-chip
