Compact photonic crystal (PhC) filters will play a vital role in wavelength division multiplexing applications and they could be the stepping stones towards the realisation of dense and multifunctional photonic integrated circuits. Bragg grating concepts are applied to PhC filters to control their response by introducing suitable phase shifts and choosing appropriate locations and magnitudes. Moreover, the variation of the PhC hole size at the input and output regions could offer an extra degree of freedom in tailoring the filter characteristics. The ability to engineer and control the filter response of photonic crystal filters is investigated in this paper.
