摘要We propose and analyze a novel ultra-compact polarization beam splitter based on a resonator cavity in a two-dimensional photonic crystal. The two polarizations can be separated efficiently by the strong coupling between the microcavities and the waveguides occurring around the resonant frequency of the cavities. The transmittance of two polarized light around 1.55 µm can be more than 98.6%, and the size of the device is less than 15 µm×13 µm, so these features will play an important role in future integrated optical circuits.
