Abstract

The invention provides a method for realizing output of an optical microcavity coupling system by temperature modulation and a coupling structure thereof. The coupling structure is mainly characterized in that one side of the coupling system is equipped with a microheater, a lead of the microheater is connected with a temperature control device, and the whole optical microcavity, a coupler and the microheater are accommodated in a packaging body by an optical transparent packaging material. The method is characterized in that output of the optical microcavity coupling system is regulated and stabilized by adjusting and controlling the temperature of the optical microcavity coupling system. The invention solves the technical problems for developing relevant devices in the technical field and provides a feasible and simple-structure technical scheme.

Description

technical field [0001] The invention belongs to the technical field of micro-opto-mechanical systems, and mainly relates to a device temperature adjustment method and its structure method, in particular to an output method of a temperature-modulated optical microcavity coupling system and its coupling structure. Background technique [0002] Whispering gallery mode (WGM) high-Q optical microcavities have been extensively studied in recent years. In this mode, the laser light propagates along the great circle of the optical microcavity with total reflection. Therefore, only a very small part of the light energy in the microcavity leaks out of the cavity, thus forming a high-Q optical mode propagating along the interface. The ultra-high Q value makes this type of optical microcavity applicable to low-threshold laser emission, high-sensitivity sensors, optical communication devices and other fields. [0003] In the application research of microcavity, it is found that the wor...
