Advantages of High Speed Photodiodes
Photodiodes with long n-Ge regions of low doping (LD) concentration exhibit fast response times (≈3 µs) and moderate responsivity (≈1.3 A W-1) in the visible range (520 nm) and in the IR range Response time (≈30 µs) and responsivity (6.4 A W-1) within (1550 nm).
