Reconfigurable mode converter based on a Sb2Se3 phase change material and inverse design
{{output}}
In this paper, we combine the inverse design with a silicon-Sb2Se3 hybrid platform to design an on-chip mode converter that converts basic modes to higher-order modes. Firstly, we present a 1 × 2 mode converter with dimensions of 4.8 × 2.7 µm2 that enables ... ...
