ABSTRACT
An eight-channel drop filter based on two-dimensional photonic crystal is proposed. A five-cascaded stub is used to receive 100% reflection feedback. The geometric parameters on the transmission spectra of the bus waveguide output port are investigated. The Fabry-Perot fibre grating theory is used to explain the influences. On the basis of the 100% reflector, a channel drop filter is designed according to the wavelength spacing in the coarse wavelength division multiplexing system. Numerical simulations demonstrate that each channel exhibits over 93% transfer efficiency.
