Figure-9 Fiber Laser with Phase Bias by Frequency Shifter

http://emcore.com/wp-content/uploads/2016/03/Delay-Lines-Application.pdf 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].
