Suppose an APD has has following parameters: dark current Ip = 1 nA, leakage cur- 10³, bandwidth rent I 1 nA, n= 0.85, M 100, excess noise factor FM, R is 10 kHz. Suppose a sinusoidally varying 850 nm signal signal having modulation in- dex m = 0.85 falls at the photodiode at room temperature (27°C). Average optical power Po = -50 dBm. Plot the value of the SNR as a function of M for 20 ≤ M≤ 100. At what value of M does the maximum SNR occurs?
