Abstract :
We present a study of amplitude noise (AN) and residual phase noise (PN) in radio-frequency (RF) photodetectors. Using a heterodyned optical source with a 1-GHz beat frequency, the AN and residual PN spectra of p-i-n photodiodes were measured and found to vary with the level of space-charge-induced RF compression, hereby quantifing the excess AN and PN in the photodetection process.
