Testing equipment for testing the performance of laser diodes

Abstract

The invention discloses a detection device for detecting performance of a laser diode, which comprises a mounting platform, a laser diode pose adjustment assembly, a laser diode clamping piece, a photodiode pose adjustment assembly, a photodiode clamping piece, a computer and a control device. When the performance of the laser diode needs to be detected, the laser diode is firstly clamped and fixed by the laser diode clamping piece, and the photodiode is clamped and fixed by the photodiode clamping piece; then, through the photodiode pose adjustment assembly, the distance between the photodiode and the laser diode is adjusted; then, through the laser diode pose adjustment assembly, the rotation angle of the laser diode is adjusted; and concurrently, the computer can receive light power signals of the laser diode detected and transmitted by the photodiode, information of the rotation angle of the laser diode is acquired through the control device, a corresponding curve is drawn, an offset angle and a divergence angle are obtained through a mapping algorithm, and the performance result of the laser diode is thus obtained.

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a detection equipment for detecting the performance of a laser diode. Background technique [0002] In the optoelectronic device industry, one of the key components is a semiconductor laser, which is also called a laser diode (LD, Laser Diode). When problems occur in optoelectronic devices, testing and analyzing the performance of semiconductor lasers can become the primary breakthrough point to solve the problem, and equipment for analyzing LD performance has also been developed. At present, most of the equipment for analyzing LD performance uses industrial CCD (charge-coupled device) for focus capture, and then uses complex algorithms to obtain analysis results. The cost of such equipment for analyzing LD performance is relatively high, which is not conducive to popularization and use. [0003] Therefore, it is necessary to provide a technical means to solve the ab...
