Abstract

Photonic crystals have a great prospect in the field of integrated optics due to their high integration and low transmission loss. In this paper, a beam splitter based on the bandgap of photonic crystal is designed and demonstrated experimentally for polarization-dependent beam splitting. The simulated radiation patterns show excellent polarization purity, with a cross-polarization level above 20 dB. Furthermore, the angle deviation of the incident and the temperature change of device have slight impact on beamsplitting. Larger shifting range of incident wavelength is allowed. What is more, the range of medium radius with good splitting effect is relatively large, which reduces the difficulty of production and processing.
