An all-optical NOT logic operation based on a chloroform filled geometrically asymmetric triangular triple-core PCF

We present an all optical NOT logic operation based on a geometrically asymmetric triangular triple core photonic crystal fiber (ATPCF), where the guiding cores are filled with highly nonlinear liquid chloroform. By employing the finite element method, necessary optical parameters of the proposed geometry are determined. The steering characteristics which attributes the critical power necessary for the control signal is obtained numerically via coupled nonlinear Schrodinger equations. Through extinction ratio calculations, the Boolean operation of NOT logic gate is illustrated with an appropriate control signal. This study accomplish the idea of an efficient NOT logic operation based on ATPCF geometry. As well as provides the sensitive dependence of geometrical asymmetry on input conditions for performing logic operations.
