Abstract

We report a novel type of dispersive structure for wavelength multiplexer/demultiplxer based on a 2D photonic crystal (PC) prism. The novel device is proposed using super dispersion of a 2D PC. Simulation is carried out to determine the angular dispersion as a function of the period. The design has been optimized to improve the performance of a system with moderate refractive index contrast. It is shown that by varying the incident angle in a wavelength range from 1.3μm to 1.5μm, a superprism effect is observed. The performance of the devices is investigated in terms of sensitivity and resolution, which would help to understand the behaviour of the superprism prior to fabrication and its integration in photonic circuits.
