Abstract

The invention discloses an optical device, and relates to the technical field of optical devices. The optical device is used for reducing the heating power consumption when a heating electrode heats an optical waveguide so as to improve the working performance of the optical device. The optical device comprises a substrate, the optical waveguide and the heating electrode, wherein the optical waveguide and the heating electrode are formed in the substrate; the optical waveguide is a snake-shaped optical waveguide and comprises a plurality of first waveguide parts and at least one second waveguide part; the plurality of first waveguide parts are distributed in the substrate along the width direction of the optical waveguide; every two adjacent first waveguide parts are connected through the corresponding second waveguide part; the heating electrode is located above the multiple first waveguide parts, the length of the heating electrode is smaller than or equal to the maximum length of the multiple first waveguide parts, and the heating electrode is used for heating the multiple first waveguide parts.

Description

technical field [0001] The invention relates to the technical field of optical devices, in particular to an optical device. Background technique [0002] The heating electrode is one of the very important components in optical devices. Specifically, when the heating electrode is energized, it can heat the optical waveguide located under the heating electrode. Based on the thermo-optic effect, the optical properties (such as the refractive index) of the heated optical waveguide will change, so as to realize the tuning of the transmission signal in the optical waveguide. [0003] However, in the process of heating the optical waveguide through the heating electrode in the existing optical device, the heating power consumption of the heating electrode is relatively large, so that the working performance of the optical device is poor. Contents of the invention [0004] The object of the present invention is to provide an optical device, which is used to reduce the heating po...
