Tunable light wave beam splitter based on fluid light guide

Abstract

A tunable light wave beam splitter based on a fluid light guide comprises the fluid light guide, an incident laser, a light beam receiving surface and a flowing-out fluid container, wherein the fluid light guide is provided with a passageway which comprises a core layer fluid inlet, two symmetric cover layer fluid inlets, a fluid microcavity and two symmetric fluid outlets, the core layer fluid inlet and the cover layer fluid inlets are all communicated with the inlet side of the fluid microcavity of which the outlet side is connected with the two fluid outlets, the fluid outlets are communicated with the flowing-out fluid container, the incident laser and the light beam receiving surface are arranged coaxially, the axes of the incident laser and the light beam receiving surface are vertical to the flowing direction of fluid, and flow rate adjusting equipment is arranged in the core layer fluid inlet and the cover layer fluid inlets and is connected with a beam splitting control module for controlling the flow rate of the fluid in a core layer and a cover layer to realize light wave beam splitting and splitting ratio control. The tunable light wave beam splitter can realize dynamic tuning and is high in integration level, simple in structure, convenient to manufacture and low in cost.

Description

technical field [0001] The invention relates to an integrated optical device, in particular to an integrated tunable optical beam splitter. Background technique [0002] The beam shaping technology includes focusing, collimation, deflection, beam splitting, coupling, etc. of the beam. Usually, adjusting the refractive index distribution of the optical medium can easily realize the focusing, collimation, deflection, beam splitting, etc. of the incident beam. control. The rapid development of microfluidic optical technology in recent years has provided us with a new method of beam shaping. The principle is to control the microscopic scale of light by controlling the flow of fluid. In view of this, microfluidic technology and systems can be introduced into the design and fabrication of fluid optical beam splitters with controllable refractive index. First, the diffusion and convection of a fluid with a higher refractive index in a fluid with a lower refractive index is used t...
