The influence of the materials that construct a one-dimensional magnetophotonic crystal (MPC) is investigated in this letter. Recently, we suggested a procedure for realizing a desirable magneto-optical performance by utilizing an MPC heterostructure. The performance to be realized consists of a desirable transmittance along with a desirable Faraday rotation angle. The synthesis procedure gives the heterostructure configuration, provided that the constituent materials have already been chosen. The heterostructure consists of dielectric Bragg gratings with a high optical contrast ratio as well as gratings with a low contrast ratio. In this letter, we show that by properly choosing the materials that compose the MPC, it is possible to reduce the length of the structure without violating the accuracy of the design. Indeed, we can reduce the length by customizing the high-contrast stacks of the MPC in such a way that they exhibit a larger contrast ratio. The length reduction is verified by two examples. In each of the examples, a desirable performance is realized by employing two different MPCs, which are composed of two different sets of materials. On the other hand, the designer can enhance the synthesis accuracy by customizing the low-contrast stacks of the MPC in such a way that they exhibit a smaller contrast ratio.

一维磁光子晶体合成中缩短长度提高设计精度

在这封信中研究了构成一维磁光子晶体 (MPC) 的材料的影响。最近，我们提出了一种利用 MPC 异质结构实现理想磁光性能的程序。要实现的性能包括理想的透射率以及理想的法拉第旋转角。合成过程给出了异质结构配置，前提是已经选择了组成材料。异质结构由具有高光学对比度的介电布拉格光栅以及具有低对比度的光栅组成。在这封信中，我们表明通过正确选择构成 MPC 的材料，可以在不影响设计精度的情况下减少结构的长度。确实，我们可以通过定制 MPC 的高对比度堆栈来减少长度，使它们表现出更大的对比度。通过两个例子验证了长度的减少。在每个示例中，通过使用由两组不同的材料组成的两种不同的 MPC，实现了理想的性能。另一方面，设计人员可以通过定制 MPC 的低对比度堆栈来提高合成精度，从而使它们表现出更小的对比度。
