基于直波导和环形谐振腔的耦合特性,设计了一种新型、高效的二维光子晶体异质结构光分束器.时域有限差分法模拟表明,该设计仅仅通过改变介质柱的折射率,使光场发生重新分布,便可实现输出能量的均分或自由分配.在通信波长范围,该设计结构尺寸小、分束角度大、分束率高,这些特性使其在光通信领域具有重要的应用前景 |

Thedesign and simulation of a new and high efficiency heterostructure beam splitter are proposed based on the coupling characteristics between the waveguide and ring resonator in two dimensional photonic crystals, The splitting properties of the beam splitter are numerically studied using the finite difference time domain method. By simply tuning dielectric constant of dielectric rods and inducing the redistribution of the power of the optical field, uniform or free splitting can be achieved. It is shown that a small dimension, a large separating angle and a high beam rate are extended to have more light output channels in the beam splitter at optical communication Wavelength. These features of the proposed heterostructure ultracompact multiway beam splitter make it a promising candidate in optical communications application |
