Fixtures for Semiconductor Optoelectronic Device Testing and Lens Coupling

Abstract

The invention provides a clamp for semiconductor optoelectronic device test and lens coupling, and relates to the field of an optoelectronic device. The clamp comprises a connecting shaft, a PCB base,a PCB and a pipe case base, wherein one end of the connecting shaft is connected with the center position of the base; the center position of the PCB base is connected with the other end of the connecting shaft; the PCB comprises four corners; the four corners of the PCB are fixedly connected with the PCB base; the pipe case base comprises four corners; the four corners of the pipe case base arefixedly connected with the four corners of the PCB; and a pipe case fixing device is arranged on the upper surface of the pipe case base. The fixation of a BOX pipe case and the connection of a circuit can be realized in a small space; and the charged test and the lens coupling are convenient.

Description

technical field [0001] The invention relates to the field of optoelectronic devices, in particular to a fixture for semiconductor optoelectronic device testing and lens coupling. Background technique [0002] Semiconductor optoelectronic devices mainly include semiconductor lasers, detectors, modulators, etc., which are the core devices of optical communication, and are also widely used in other fields, such as laser radar, laser gas detection and so on. Accurate testing of semiconductor optoelectronic devices and precise coupling of lenses are extremely important for device performance characterization and parameter analysis, and are also important for subsequent applications such as optical communication modules. Higher coupling accuracy means that the same power needs to be achieved. The energy consumption is lower. For example, semiconductor lasers used for gas detection have stricter requirements on luminous power. Semiconductor optoelectronic devices need to test and ...
