Investigation of optical pulse coupling through the nitrobenzene filled photonic crystal fiber coupler — A projection operator approach

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 is an excellent analytical tool, which provides us a greater control over the study of individual pulse parameter dynamics. The obtained results clearly demonstrates the mechanism of the coupling and pulse parameter dynamics through the dual core couplers.
