Abstract

The invention provides an optical fiber micro composite lens. It is characterized in that it is prepared by coaxial double waveguide optical fiber through thermal diffusion. The optical fiber microcomposite lens is prepared by thermal diffusion in a constant temperature field. After the core dopant of the finely designed coaxial dual waveguide fiber is diffused, the refractive index distribution becomes a circumferentially symmetrical double hump distribution, which can be equivalent to for the micro-composite lens. The invention provides a fiber-integrated fiber micro-composite lens, which has the advantages of simple manufacture and low cost. The invention can be used for the preparation of fiber-integrated micro-combined lenses, and can be widely used in fields such as micro-endoscopes based on fiber-integrated micro-combined lenses, cell biological optical fiber imaging systems, optical fiber optical tweezers systems, and miniature drones.

Description

(1) Technical field [0001] The invention relates to an optical fiber micro-combined lens, which can be used for the preparation of fiber-integrated micro-combined lenses, and can be widely used in micro-endoscopes, cell biological optical fiber imaging systems, and optical fiber optical tweezers systems based on fiber-integrated micro-combined lenses , Micro-UAV and other fields. (2) Background technology [0002] With the development of modern industry and science and technology, people have gradually entered the information age. The rapid development of information technology requires that a complete information system can realize as many functions as possible in as small a space as possible, which requires the devices that realize various functions to be as small as possible, and to develop in the direction of miniaturization and miniaturization. [0003] Fiber-integrated micro-optical components have the advantages of small size, light weight, flexible design and manufa...
