Multistability and Switching in Oppositely Directed Saturable Coupler
K. Nithyanandan, A. K. Shafeeque Ali, M. P. M. Nishad +3
We report a novel optical multistability in two core oppositely directed saturable coupler (ODSC) with negative index material (NIM) channel. The dynamics are studied using the Lan…
