Low-loss broadband nonvolatile 2× 2 switch based on Sb2Se3 for programmable silicon photonics
CLEO: Science and Innovations, 2022•opg.optica.org
We demonstrate a broadband low-loss nonvolatile 2× 2 silicon directional coupler switch
based on phase-change material Sb 2 Se 3. The switch has a low insertion loss of~ 0.5 dB,
a compact footprint of~ 41 µm, and less than-10 dB crosstalk across~ 33 nm bandwidth
around 1550nm.
