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. The channeliser is based on a vernier architecture. Thin-film heaters on the surface of the waveguide filters enabled the resonant frequency of the filters to be tuned. Filter 3dBe bandwidths of ∼1 GHz were measured.
