Abstract : The applicability of photonic band gap structures in high Q resonators has been studied. A review of numerical simulations, experiments, and system design studies are presented. These results confirmed the technical feasibility of utilizing, 2-D photonic band gap structures with high temperature superconducting end plates as high Q resonators for fabricating low phase noise oscillators. A particularly important result of the numerical simulations is that inverse structures (dielectric host with air holes) exhibited useful photonic band gap properties. Experiments performed at 10 GHz demonstrated two methods of modulating the defect mode frequency. A supplier of high temperature superconducting films, suitable for millimeter-wave photonic band gap resonators has agreed to collaborate with Tristan Technologies in a Phase II effort. Potential commercial and government applications for photonic band gap resonators with high temperature superconducting end plates have been identified
