Abstract

In the present paper the modified effective-index model of photonic-crystal waveguide is proved and presented. This model allows to reduce the three-dimensional numerical analysis to the two-dimensional consideration of the waveguiding due to representing of the waveguide as its step-index analog with the cladding region described by the effective refractive index of two-dimensional photonic crystal (PC) and the effective core size. The effective core size allowing equivalent description of waveguiding properties in the PC waveguide using the modified effective-index model and its numerical approximation are numerically defined. The obtained data have been used for numerical investigation of waveguide couplers formed by tapered photonic crystal fiber (PCF). It was shown that the couplers have smaller loss in comparison with couplers made by tapered step-index fiber.
