Phase-induced intensity noise in optical interferometers excited by semiconductor lasers with non-Lorentzian lineshapes

摘要

Previously obtained results for the covariance, power spectrum, and variance of the phase-induced intensity noise (PIIN) at the output of optical systems with multiple paths are modified to include the effect of non-Lorentzian source lineshapes. In the coherent limit (delaysource coherence time), the source relaxation oscillations significantly change the spectral shape of the PIIN at the output of such multiple-path architectures.
