Abstract The impact of local oscillator intensity noise on the performance of an optical phase‐diversity FSK receiver using a delay‐and‐multiplying discriminator is analyzed. Given the data rate, frequency deviation, laser linewidth, RIN noise, and thermal noise, we can obtain the minimum received signal power together with the corresponding optimal local oscillator power to achieve the required BER. Numerical results with system parameters given in [1] show that (P L ) opt is ‐1.46 dBm for RIN = ‐160 dB/Hz and ‐6.4 dBm for RIN = ‐150 dB/Hz when the thermal noise is 9 × 10 −24 A 2 /Hz.
