Method of making optical planar waveguide

Abstract

The invention discloses a method of making an optical planar waveguide. According to the invention, the cold welding process is used for bonding a laser crystal waveguide strip and an electro-optical crystal waveguide strip, excellent heat dissipation of a device at work can be achieved through accurate pressure control and selection of appropriate bonding material and substrate material, and internal stress accumulation due to uneven pressure can be eliminated. The making method is mature and high in consistency and can be batched.

Description

technical field [0001] The patent of the present invention relates to the field of optical waveguide technology, in particular to a cold pressure welding process for bonding laser crystals and components. Background technique [0002] Different materials have different physical properties, such as mobility, optical absorption properties, thermal conductivity, and mechanical properties. For an application, one material often cannot meet all the required optical properties, so two or more materials need to be integrated. Over the past few decades, people have been exploring ways to integrate different materials to create more powerful and superior devices. [0003] Optical fiber and flat optical waveguide have always been two important dielectric cavities in the field of laser transmission. The manufacturing technology of optical fiber is quite mature, but the processing technology of optical planar waveguide plate is not very mature. Although there are various methods, it ca...
