WebApr 12, 2024 · We propose a perfectly vertical coupling scheme based on metasurface deflectors (meta-deflectors) and grating couplers (GCs). An approach for optimizing the GCs based on the Gaussian-fitting using the genetic algorithm is proposed. An meta-deflector based on amorphous silicon (a-Si) pillars is designed to the optimal coupling angle of the … WebJan 7, 2024 · Here, by exploiting an asymmetric directional coupler design, we demonstrate nonvolatile PCM-clad silicon photonic 1 × 2 and 2 × 2 switches with a low insertion loss of ∼1 dB and a compact coupling length of ∼30 μm while maintaining a small crosstalk less than −10 dB over a bandwidth of 30 nm.
