- In this paper, we study the bistability characteristics of chalcogenide nonlinear FBGs. The effect of length and third order nonlinearity on On-Off switching ratio and intensity distribution in FBG are investigated numerically. We obtained that there exist an optimum FBG length, that on-off switching ratio is maximized and is independent of the third order nonlinearity.
