Abstract
The invention is based on a thermo-optic phase modulator comprising, in a stack, a waveguide, an encapsulation layer and a heating element configured to heat the waveguide, said modulator being bordered by first and second trenches. Advantageously, the waveguide, the encapsulation layer and the heating element, each have first and second flanks forming at least partially the flanks of the trenches. The flanks of the waveguide, of the encapsulation layer and of the heating layer thus open directly into the trenches bordering the modulator. The invention is also based on a method for producing such a compact modulator.
