Abstract
We experimentally investigated the transmission variation of a nonlinear optical loop mirror (NOLM). We analyzed the transmission evolution of the NOLM based on the input intensity. The NOLM is formed by a symmetrical coupler, 500 m of highly twisted low-birefringence fiber and a quarter-wave retarder plate in the loop. If we rotate the quarter-wave retarder plate is possible to change the transmission behavior. Using circular polarization of the input beam is possible to get a high contrast between the maximum and minimum of the transmission. With this characteristic, we have the possibility to reduce the amplitude fluctuations and the pedestal in a train of optical pulses.
