The characteristics of circular resonators that are based on PC reflector, were studied using FDTD algorithm and a coupled-wave approach. The Bragg confinement enabled the realization of compact resonators and exhibited both the large free spectral range (FSR) and high Q-factor. The circular disk resonators that utilized photonic crystal reflectors were suitable to great variety of realization concepts, as compared to circular symmetric structures. The bending losses of the PC circular resonator were shown to be decoupled from the FSR and the actual resonance wavelength of the cavity.
