Abstract
Photonic crystal device based on silicon nitride resonant cavity and acting as a band pass filter is presented. The devise consists of an incoming waveguide, coupling dipole cavity and outgoing waveguide. High transmission for resonant frequency and sufficient attenuation for other frequencies is achieved. Results of band gap and transmission calculations as well as the fabrication approach and fabricate structures are presented. Measurement setup to experimentally prove the predicted optical properties is presented.
