Abstract
Abstract : We carried out detailed studies of Fabry-Perot resonances ( transmission band edge resonances) in periodic layered structures involving birefringent layers. We have shown that the presence of birefringent layers with misaligned in-plane anisotropy can dramatically enhance the performance of the photonic-crystal resonator. It allows us to reduce its size by an order of magnitude without compromising on its performance. The key characteristic of the enhanced slow-wave resonator is that the Bloch dispersion relation of the periodic structure displays a degenerate photonic band edge. Such a situation can be realized in specially arranged stacks of misaligned anisotropic layers. On the down side, the presence of birefringent layers results in the slow-wave resonance being coupled only with one elliptic polarization component of the incident wave, while the other polarization component is reflected back to space.
