Embodiment Construction

[0032] In the following, only some exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present disclosure. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive.

[0033] The inventors of the present disclosure understand that the modulation efficiency of the thermo-optic phase modulation module in the related art is still not ideal due to the large heat loss, and therefore, the improvement of the modulation efficiency of the optical modulator is also limited.

[0034] Based on this, embodiments of the present disclosure provide a thermo-optic phase modulation module and an optical modulator, so as to improve the modulation efficiency of the thermo-optic phase modulation module, and further improve the modulation efficiency of the optical modulator.

Abstract

The invention provides a thermo-optic type phase modulation module and an optical modulator, and relates to the technical field of optical communication. The thermo-optic phase modulation module includes: a substrate; an isolation layer which is located on the substrate; a first waveguide which is positioned on the isolation layer; and at least one heating element which is located on the isolation layer and is not overlapped with the first waveguide in the direction perpendicular to the bottom surface of the substrate; wherein the thermo-optic phase modulation module has a plurality of side thermal insulation grooves extending downward from the top surface and exposing the substrate, the plurality of side thermal insulation grooves are arranged around the first waveguide and the at least one heating element. According to the technical scheme, the modulation efficiency of the thermo-optical phase modulation module can be improved, and then the modulation efficiency of the optical modulator is improved.

Description

technical field [0001] The present disclosure relates to the technical field of optical communication, in particular to a thermo-optical phase modulation module and an optical modulator. Background technique [0002] Optical communication has rapidly developed into the main form of information transmission due to its advantages of frequency bandwidth and large capacity. To realize optical communication, optical modulation and demodulation must be carried out. [0003] A phase modulator is a device for modulating the phase of an output optical signal, which may include one or more phase modulation modules. Based on different modulation mechanisms, the phase modulation module can be, for example, an electro-optic phase modulation module based on the electro-optic effect or a thermo-optic phase modulation module based on the thermo-optic effect. The modulation speed of the electro-optic phase modulation module is fast, but its phase modulation range is small, which leads to li...
