Provided is a method for detecting the performance of a laser diode. The method is based on an apparatus composed of an installing platform, a laser diode position and pose adjusting assembly, a laser diode clamp, a photodiode position and pose adjusting assembly, a photodiode clamp, a computer, and a control device. When the performance of the laser diode is required to be detected, the laser diode is clamped by the laser diode clamp and the photodiode is clamped by the photodiode clamp; the distance between the photodiode and the laser diode is adjusted by the photodiode position and pose adjusting assembly; the rotary angle of the laser diode is adjusted by the laser diode position and pose adjusting assembly; further, the computer receives a detected optical power signal, transmitted from the photodiode, of the laser diode and information of the rotary angle of the laser diode acquired by the control device, draws a corresponding curve, and derives a deviation angle and a divergence angle by means of a drawing algorithm so as to obtain a performance result of the laser diode.
Description
technical field [0001] The invention relates to the technical field of detection equipment, in particular to a detection method 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. When this type of equipment for analyzing LD performance is relatively expensive, it is not conducive to popularization and use. Moreover, Its detection operation is cumbersome, time-consuming and costly. [...
