Abstract

The application provides a high temperature resistant type II optical waveguide processing method and system and a high temperature resistant type II double-wire waveguide, which relate to the technical field of waveguide preparation. The invention can solve the problem of how to quickly obtain the high temperature-resistant type II double-wire waveguide. The method includes: obtaining a Gaussian beam; using a spatial light modulator to perform focal field shaping on the Gaussian beam to obtain a three-dimensional optical focal field with bifocal light intensity distribution along the laser propagation direction; using the laser beam after focal field shaping to treat The processed samples were scanned multiple times in situ to obtain a type II double-wire waveguide with high temperature resistance and low loss.

Description

technical field [0001] The present application relates to the technical field of optical waveguide preparation, in particular to a high temperature resistant type II optical waveguide processing method, system and high temperature resistant type II bifilar waveguide. Background technique [0002] The waveguide is the basic unit of the integrated chip. For extreme fields such as aerospace, the device is often required to withstand high temperatures. However, the optical waveguides often used by researchers for direct writing of glass and polymer materials have a limited operating temperature. High-performance optical waveguides and integrated photonic devices are very necessary in extreme fields such as aerospace. Type I waveguide is easy to be erased at high temperature and difficult to retain, so the related field adopts type II bifilar waveguide induced by stress. [0003] The waveguide prepared by femtosecond laser direct writing has the advantages of high flexibility an...
