Abstract

In this paper a Metal-Insulator-Metal configuration based electro-optic microring resonator is designed and simulated by using Bismuth Ferrite and Germanium Antimony Telluride for wavelength filtering, switching and modulator applications. The device works on the phenomena of change in refractive index of the active materials when electric field is applied. Initially, switching and filtering is demonstrated by using bismuth ferrite as an active material inside the ring resonator. Later on, an additional layer of GST is added to the ring resonator resulting in increased light confinement inside the ring resonator in the amorphous state of GST layer. Due to this, resonant dips sharpens which improves the quality factor of the device up to 154. By optimizing the device's structural parameters, a modulation depth of 23.11 dB is achieved with a low loss of 1.6 dB. Additionally, these innovative SPPs plasmonic waveguide structures can accommodate various filtering requirements and have good filtering efficiency.

用于纳米光子学应用的 GST 和 BFO 辅助微孔谐振器

本文利用铁氧体铋和碲化锗锑设计并模拟了一种基于金属-绝缘体-金属配置的电光微波谐振器，用于波长滤波、开关和调制器应用。该装置利用施加电场时活性材料折射率变化的现象工作。最初，通过在环形谐振器内使用铁氧体铋作为活性材料来演示开关和滤波。后来，在环形谐振器中又添加了一层 GST，从而在 GST 层的非晶态下增加了环形谐振器内部的光局限性。因此，谐振骤降变得尖锐，从而将器件的品质因数提高到 154。通过优化器件的结构参数，可实现 23.11 dB 的调制深度和 1.6 dB 的低损耗。此外，这些创新的 SPPs 质子波导结构还能满足各种滤波要求，并具有良好的滤波效率。
