<title>Using a depolarizer to reduce the effect of phase-induced intensity noise in fiber optics bit rate limiters</title>

Abstract

A Lyot depolarizer is used in a bit-rate-limiter of the Mach-Zehnder type in order to reduce the phase induced intensity noise, which otherwise, sets a floor on the bit error ratio. Results show an improvement of 3dB, at the expense of longer arms and a more complicated design.
