Abstract :
An apodised sampled grating was fabricated using an InGaAsP/InP deep-ridge waveguide with vertical-groove surface grating for use in a tunable optical filter. The fabricated grating exhibited a comb-like filter response with a relatively wide transmission bandwidth of 52 GHz and a high extinction ratio of 15 dB.
