Ultra-compact, ultra-low-loss and broadband 2 × 2 nonvolatile optical switch based on Sb2Se3 phase change material
{{output}}
We propose an ultra-compact broadband 2 × 2 nonvolatile optical switch based on two adjacent silicon waveguides embedded with a low-loss phase change material (Sb2Se3). In the crystalline state of Sb2Se3, the two waveguides in the middle section are not coupl... ...
