Abstract :
Optical bistability in a nonlinearly reflective fiber grating through the mode coupling between the LP01 and counter propagation LP02 modes (i,e., the reflective LP01&rlhar2;LP02 mode converter) is investigated by using the coupled-mode theory. Both the transmissive and the reflective properties of this nonlinear device are analyzed, which show that the output-versus-input relation exhibits the optical bistability. The switching power and the bistable hysteresis performances are also discussed. In addition, the comparison between the nonlinearly reflective mode converter (LP01&rlhar2;LP02) and the nonlinear fiber Bragg grating reflector (i,e., the LP01 and counter-propagation LP01 modes) is also presented. It is shown that the former has much lower switching power than the latter
