WebA conventional way of achieving phase shifting in optical fiber is by implementing the nonlinearity of the fiber itself. However, the drawback of this method is the need for either a long conventional fiber or a special nonlinear fiber thus making it inconvenient to be used in small compact devices and limiting its tuning capability [2]. WebIn that case, the phase modulation often needs to be strong in order to obtain a large number of optical sidebands. In data transmitters of optical fiber communication systems, phase modulators can be used for encoding the transmitted information. An example is the method of phase shift keying.
