Abstract:
1. An optical waveguide device comprising: an optical waveguide having a core configured to propagate light and a clad surrounding the core; an optical modulator joined to the optical waveguide, the optical modulator having at least one element affecting the light propagating in the core; a spacer disposed between the optical modulator and the optical waveguide, for maintaining a predetermined distance there between, the spacer comprises a first portion disposed on a first side of the core and a second portion disposed on a second side of the core; and a resin layer disposed between the optical waveguide and the optical modulator and between the first portion and second portion of the spacer; wherein the at least one element is a heater that changes the refractive index of the core making use of a thermo-optical effect.
