Abstract In this paper, we analyze the relative stability of optical injection phase-locked loop (OIPLL) in terms of the phase margin considering loop-delay into account. Phase margin of first- and second-order OIPLL are calculated as a function of loop-delay, damping factor and other parameters of the loop. The effects of optical injection on damping factor and phase margin of the loop are shown. It is observed that the OIPLL has better stability than the conventional optical phase-locked loop (OPLL) in presence of loop-delay.
