A Segmented Heater-Driven, Low-Loss, Reconfigurable Photonic Phase-Change Material-Based Phase Shifter
Ranjeet Dwivedi, Agraj Yadav, Regis Orobtchouk +4
Phase-change material (PCM)-based non-volatile multilevel phase shifters are key components in photonic integrated circuits. Electrically, multiple phase levels can be encoded by c…

An Ultra-low-loss Compact Phase-Change Material-based Hybrid-mode Interferometer for Photonic Memories
Ranjeet Dwivedi, Fabio Pavanello, Regis Orobtchouk
We propose a novel hybrid mode interferometer (HMI) leveraging the interference of hybridized TE-TM modes in a silicon-on-insulator (SOI) waveguide integrated with a GeSe phase cha…
