Abstract:
A one-dimensional photonic bandgap mirror PBM has been designed consisting of periodically alternating planar quarter-wavelength layers of a high-refractive index dielectric and low-refractive index material e.g. vacuum. A V-shaped folded Fabry-Perot Interferometer was set up with two scaled PBMs and a spherical metal mirror to provide a stable resonator design. The PBMs consisted of polystyrene and air as dielectrics and were designed for a center frequency of 23.44 GHz. The transmission characteristics of the FPI was measured for different numbers of layers in the PBMs. The reflectivity of the PBMs was derived from the cavitys chromatic resolving power. The measured reflectivity and bandwidth are compared with theoretical expectations taking into account resonator losses and absorption in the dielectrics.
