Phase-change materials (PCMs) have emerged as promising active elements in silicon (Si) photonic systems. In this work, we design, fabricate, and characterize a hybrid Si-PCM optical switch. By integrating vanadium dioxide (a PCM) within a Si photonic waveguide, in a non-resonant geometry, we achieve ~10 dB broadband optical contrast with a PCM length of 500 nm using thermal actuation.
相变材料(PCM)已成为硅(Si)光子系统中很有前景的有源元件。在这项工作中,我们设计、制造并表征了一种混合硅 - 相变材料光开关。通过在非谐振几何结构的硅光子波导中集成二氧化钒(一种相变材料),利用热驱动,我们在相变材料长度为500 nm的情况下实现了约10 dB的宽带光学对比度。
