P21 – Numerical investigation of optical bistability in inhomogeneous PT -symmetric gratings

Sudhakar S., Vignesh Raja S., Govindarajan S.

Customizing the nonlinear profile along the direction of propagation helps in the realization of low-power all-optical switches. The switching intensities are extremely low (<0.01) in the broken regime provided that the light launching direction is right. It is believed that the switching intensities in the broken regime are always higher than that of the unbroken […]
