Beschreibung
Zusammenfassung:	The utility model discloses a thermo-optical phase shifter, a waveguide joint and an optical computing network, the thermo-optical phase shifter comprises a waveguide layer, a compression layer and a heating member, and the waveguide layer is used for introducing light waves; the compression layer is attached to the waveguide layer, the refractive index of the compression layer is larger than that of the waveguide layer, and the thermo-optical coefficient of the compression layer is larger than that of the waveguide layer; the heating element is arranged to heat the compression layer so that the compression layer adjusts the phase of the light wave. The waveguide layer and the compression layer which are attached to each other are arranged, and the refractive index of the compression layer is set to be larger than that of the waveguide layer, so that light waves entering the waveguide layer can be compressed to the compression layer. The thermo-optical coefficient of the compression layer is set to be larger
