We propose a novel highly nonlinear chalcogenide filled twin core photonic crystal fiber coupler (PCFC) for applications in all optical controlled devices. From the proposed coupler geometry, the necessary optical parameters namely, effective refractive index, dispersion, nonlinearity, coupling length and extinction coefficient are calculated by using the finite element method (FEM) at 1550 nm. The...
We explore all-optical pulse coupling dynamics of nitrobenzene filled dual core photonic crystal fiber coupler (LCPCF). The optical characteristics of the proposed design is obtained using the finite element method (FEM). The optical pulse dynamics through the proposed coupler model described by a set of coupled nonlinear Schrödinger equation has been studied by projection operator method (POM). POM...
