Pneumatic pressure grinding mechanism and grinding method for optical fiber and lithium niobate wafer

Abstract

The invention discloses a fiber and lithium niobate wafer pneumatic pressurized grinding mechanism and grinding method, including a three dimensional positioning device, a pneumatic device, and a clamping mechanism, a z-axis moving mechanism switching board of the three dimensional positioning device is connected with the pneumatic device, and the clamping mechanism is arranged on the pneumatic device. A fiber and lithium niobate wafer is clamped by the clamping mechanism and is connected with a cylinder piston rod through an adjusting slide rod and a beam type force transducer. The three dimensional positioning device can realize the accurate positioning and grinding micro-feeding of a lithium niobate wafer clamping tool, the pneumatic device makes the change of the grinding pressure a gradually changing process, and the lithium niobate wafer clamping tool can stably and rapidly clamp a lithium niobate wafer. The grinding pressure during the grinding of the lithium niobate wafer is constant, and the changing process of the grinding pressure is a gradually changing process, so that the grinded end face quality is guaranteed, and the grinding process is stable and reliable; and meanwhile, the fiber end face of the grinded lithium niobate wafer can be conveniently observed.

Description

technical field [0001] The invention relates to the technical field of optical fiber and lithium niobate wafer grinding, in particular to a pneumatic pressure grinding mechanism and grinding method for optical fiber and lithium niobate wafer. Background technique [0002] The existing optical fiber polishing machine can grind the end face into a certain shape when grinding the fiber ferrule and bare optical fiber. In order to couple the optical signal passing through the optical fiber as much as possible, the flatness and Roughness puts forward higher requirements. The lithium niobate integrated optical phase modulation device used in the fiber optic gyroscope (referred to as a multifunctional integrated optical chip abroad, MFIOC) refers to a waveguide device with the functions of a Y-shaped beam splitter, a polarizer and a phase modulator. The three functional components are integrated on the same chip, and its excellent characteristics ensure the realization of high-perf...
