Inverse design of compact nonvolatile reconfigurable silicon photonic devices with phase-change materials.

ABSTRACT: In the development of silicon photonics, the continued downsizing of photonic integrated circuits will further increase the integration density, which augments the functionality of photonic chips. Compared with the traditional design method, inverse design presents a novel approach for achieving compact photonic devices. However, achieving compact, reconfigurable photonic devices with the inverse design that employs the traditional modulation method exemplified by the thermo-optic effect poses a significant challenge due to the weak modulation capability. Low-loss phase change materials (PCMs) exemplified by Sb₂Se₃ are a promising candidate for solving this problem benefiting from their high refractive index contrast. In this work, we first developed a robust inverse
