Abstract

An optical waveguide chip coupling testing clamp comprises a chip supporting bench and a supporting structure used for supporting the chip supporting bench. The chip supporting bench is provided with a chip clamp. The chip clamp comprises a plurality of chip fixing adjusting knobs and chip fixing clamps respectively fixed to each chip fixing adjusting knob. The plurality of chip fixing clamps are arranged in such a manner that a chip to be fixed is surrounded to the central region, and the chip fixing adjusting knobs are capable of adjusting fixing positions and fixing angles of the chip fixing clamps relative to the chip. The optical waveguide chip coupling testing clamp can be used for clamping and fixing the optical waveguide chip and adjusting the chip fixing angle when end surface coupling is carried out on an optical fiber and an optical waveguide, is suitable for the optical waveguide chips various in shape and size, and has the advantages that the structure is simple and novel, the chip is stably and firmly clamped, the attitude of the chip is flexibly adjusted, the clamped chip is easy to mount, dismount and replace, the operation is easy and convenient, the application range is wide, etc.

Description

technical field [0001] The invention relates to the field of optical waveguide technology, in particular to an optical waveguide chip coupling test fixture, which is used for clamping and fixing the optical waveguide chip and adjusting the height, tilt and pitch angle of the optical waveguide chip when the optical fiber is coupled with the end face of the optical waveguide. Background technique [0002] Entering the 21st century, with the upgrading of computer technology and the rise of the information industry, the wave of information revolution has entered a new stage. Human beings are moving from the Internet where everyone is connected to the Internet where everything is connected. Information age of big data. People have a higher demand for information transmission speed, which brings new challenges to the existing network system, the bandwidth, reliability, confidentiality and low power consumption of integrated circuit chips, and the concept of all-optical network thu...
