在本文中，我们提出了两个四端口的光环行器，分别为TE和TM模式。利用氮化硅基片上Ce：YIG脉冲激光沉积技术的最新进展，设计了两种集成环行器，可用于集成光学中的解复用器、输入/输出放大器隔离器和输出激光隔离器。所提出的器件联合收割机将低损耗氮化硅波导的优点与磁光材料的非互易特性相结合。为了最大化非互易相移，对环形截面进行了优化，最后用传输矩阵法计算了散射系数。氮化硅的材料稳定性和折射率规律性，小的微环足迹和高波长选择性使这些器件特别有吸引力。(C)2013年美国光学学会
In this paper, we present two four-port optical circulators for TE and TM modes, respectively. Exploiting the recent technological development concerning Ce:YIG pulse laser deposition on silicon nitride platform, we design two integrated circulators, which can be used to implement several functions in integrated optics, such as de-interleavers, input/output amplifier isolators and output laser isolators. The proposed devices combine the benefit of low loss silicon nitride waveguides with the non-reciprocal properties of magneto-optical materials. The ring cross-section has been optimized in order to maximize the non-reciprocal phase shift and finally the scattering coefficients have been computed using the transfer matrix method. The material stability and refractive index regularity of silicon nitride, the small micro-ring footprint, and the high wavelength selectivity make these devices particularly attractive.
