Abstract: We research experimentally the configuration of a nonlinear optical loop mirror, with an imbalanced coupler, highly twisted low birefringence fiber and a variable wave retarder (VWR) inserted into the loop. The use of the variable wave retarder allows the easy adjustment of the nonlinear dependence of the NOLM transmission. The mechanism of VWR consists of applying an adjustable pressure on the optical fiber inside the loop to have different values of VWR through simple way. The nonlinear transmission of NOLM for different values of ? and different amplitude of the input pulse were presented. The experimental results showed that VWR is a device that allows a simple adjustment of the nonlinear characteristic of the NOLM.
