Abstract: Simulation analysis of proposed optical costas loop has been investigated considering strong nonlinearity of loop and finite loop delay through phase subtraction. Prime attention has been given on inherent laser phase noise due to random spontaneous emission and shot noise related to photo detection process. The stringent laser linewidth requirements for promising receiver has been relaxed up to 8.0 MHz for each laser considering 3.3° RMS phase error and power sensitivity improvement is realized introducing an extra optical phase modulator at VCO laser output.
