摘要

在本文中，我们提出了一种基于sb2se3负载波导中多模干扰的非易失性开关。通过在多模干涉耦合器内实现低损耗相位控制，该设计有效地管理了单个相变周期内的自成像相移长度。制作的多路复用光开关具有令人印象深刻的性能特征，包括插入损耗低至~ 1.5 dB，紧凑的长度为~ 35 μm，在35 nm带宽下，非晶和晶体状态的串扰最小，低于-6 dB。通过Sb2Se3相变重新配置光路由的能力为光学现场可编程门阵列和高密度光子处理器开辟了新的途径。

Non-volatile optical switch based on Sb₂Se₃-loaded three-mode interference.

In this Letter, we propose a non-volatile switch based on multimode interference in an Sb₂Se₃-loaded waveguide. By implementing low-loss phase control within a multimode interference coupler, this design effectively manages the self-imaging phase shift length during a single phase change cycle. The fabricated multiplexed optical switch exhibits impressive performance characteristics, including a low insertion loss of ∼ 1.5 dB, a compact length of ∼35 μm, and minimal cross talk below -6 dB over a 35 nm bandwidth for both the amorphous and crystalline states. The ability to reconfigure light routing via Sb₂Se₃ phase transitions opens new avenues for optical field-programmable gate arrays and high-density photonic processors.
