Ultra-low loss hybrid ITO/Si thermo-optic phase shifter with optimized power consumption

Parra Gómez, Jorge; Hurtado Montañés, Juan; Griol Barres, Amadeu; Sanchis Kilders, Pablo (The Optical Society, 2020-03-30)

[EN] Typically, materials with large optical losses such as metals are used as microheaters for silicon based thermo-optic phase shifters. Consequently, the heater must be placed far from the waveguide, which could come ...
