Abstract

Embodiments of the present invention disclose a waveguide structure, an optical device, and a method for manufacturing the waveguide structure. The waveguide structure comprises: a first dielectric layer; a core layer stacked on the first dielectric layer, wherein the refractive index of the core layer is greater than the refractive index of the first dielectric layer; a second dielectric layer stacked on the core layer, wherein the second dielectric layer comprises a groove, the opening of the groove faces away from the core layer, and the refractive index of the second dielectric layer is smaller than the refractive index of the core layer; and an absorption layer covering the outer surface of the second dielectric layer, wherein the absorption layer is in contact with the side wall of the groove and the bottom of the groove, and the absorption layer has a non-linear saturation absorption property.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of optical communication, and in particular, to a waveguide structure, an optical device, and a manufacturing method of the waveguide structure. Background technique [0002] Femtosecond lasers are one of the core devices in the field of optical communication technology, which can generate femtosecond-level pulsed light sources with a wide range of applications. Chip-scale femtosecond lasers based on nonlinear saturable absorbers can form ultrashort pulses, and have the advantages of high stability and small size. In the related art, when the modulation depth of the femtosecond laser is changed, intrinsic loss will be introduced to reduce the performance of the femtosecond laser. Contents of the invention [0003] In view of this, embodiments of the present invention provide a waveguide structure, an optical device, and a method for manufacturing the waveguide structure. [0004...
