Abstract
A nonlinear transmission system comprising a polarization maintaining (PM) fiber and a polarizer, based on the extreme sensitivity of the state of polarization of transmitted light on various parameters, such as the temperature, the optical power input to the fiber. Passive stabilization is achieved by simply terminating the PM fiber by a polarizer at a selected angle. Active stabilization of the optical length of the PM fiber is achieved by feeding back the transmitted into the control of optical power sent through the fiber.
