A waveguide grating have been designed suitable for Coarse Wavelength Division Multiplexing applications in which the refractive index is perturbed by the spatial tailoring of the band gap with fluorine ion implanted quantum well intermixing of the In 0.95 Ga 0.05 As 0.10 P 0.90 /InP multi quantum well structure. The gratings have been modeled using coupled mode theory and diffusion equations and Schrödinger wave equations are used to model quantum well energy while interdiffusion. A four channel waveguide grating from 1,550 to 1,610 nm at a span of 20 nm have been simulated with a channel bandwidth of 13 nm and a cross talk of −5 to −10 dB.
