Embodiment 1
[0059] The cross-sectional schematic view of the elliptical core fiber of this embodiment, as Figure 5 shown. 51 is the cladding of the elliptical core optical fiber, and 52 is the elliptical core of the elliptical core optical fiber.
[0060] The preparation steps of the fiber-integrated orthogonal biaxial aspheric fiber microlens in this embodiment are as follows:
[0061] The first step is to finely design the elliptical core fiber, including the design of the geometric size, dopant type, and numerical aperture of the elliptical core. The parameters of the carefully designed elliptical core fiber in this embodiment are that the cladding radius is 62.5 μm, the a-axis radius of the elliptical core is 17.5 μm, the b-axis radius is 10 μm, and the numerical aperture is 0.14. The dopant species of the elliptical core fiber is germanium.
[0062] In the second step, thermal diffusion treatment is performed on the elliptical core optical fiber. A section of elliptical core fib...

Abstract
The invention provides an orthogonal biaxial aspheric fiber microlens. It is characterized in that it is prepared by thermal diffusion of elliptical core optical fiber. Orthogonal biaxial aspheric fiber microlens is prepared by thermal diffusion in a constant temperature field. After the elliptical core dopant of the finely designed elliptical core fiber is diffused, the refractive index distribution becomes a non-circumferentially symmetrical quasi-Gaussian distribution. It can be equivalent to a microlens. The invention provides a fiber-integrated orthogonal biaxial aspheric fiber microlens, which has the advantages of simple manufacture and low cost. The present invention can be used for the preparation of fiber-integrated microlenses, and can be widely used in micro-endoscopes based on fiber-integrated orthogonal biaxial aspheric fiber optic microlenses, cell-biological optical fiber imaging systems, optical fiber optical tweezers systems, and miniature unmanned aerial vehicles and other fields.
Description
(1) Technical field [0001] The invention relates to an orthogonal biaxial aspheric fiber optic microlens, which can be used in the preparation of fiber-integrated microlenses, and can be widely used in microendoscopes, Cell biological optical fiber imaging system, optical fiber optical tweezers system, 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 manufacturing, low manufacturing cost, and easy array and...
