Abstract

An integrated optical chip based on an array of silica waveguide Fabry-Perot filters with dielectric mirrors has been fabricated as part of a photonic microwave channelising receiver. Thin-film heaters enabled the resonant frequency of the filters to be tuned. Filter 3 dBe bandwidths of ∼1 GHz were measured.
