Problems solved by technology

[0002] At present, the principle of LD is to inject current into the semiconductor PN junction, realize the reverse distribution of particle number, generate stimulated radiation, and then use the positive feedback of the resonator to realize the laser oscillation generated by optical amplification. The laser diode has high efficiency and small size. , long life, but its output power is small (generally less than 2mW), poor linearity, and poor monochromaticity, so its application in cable TV systems is greatly limited, and it cannot transmit multi-channel, high-performance analog signals

Abstract

The invention discloses a fixing base for a laser diode patch. The fixing base comprises a base and a fixing groove, the fixing groove is formed on the surface of the upper end of the right side of the base, and threads are arranged on the surface of an inner ring of the base. A fixing device and a detection device are arranged at the upper end of the base, and the fixing device comprises a fixingbase, an LED lamp strip, a partition plate, a clamping groove, a positive electrode contact, a sliding ring, a brush piece and a spring copper piece. The fixing seat is screwed and fixed in the fixing groove through the threads, a spring copper sheet is fixed in the middle of the surface of the fixing groove through a conductive plate, and a contact is fixed at the upper end of the spring coppersheet. According to the invention, the fixing seat is screwed and fixed in the fixing groove, so that the fixing base can be replaced conveniently to process the diodes of different sizes; the LED lamp strip arranged on the surface of the upper end of the fixing base can play a role in illumination, and the arranged detection device can detect the machined diodes, so that the defective products are avoided, and the surface mounting work of the diodes is easier.

Description

technical field [0001] The invention relates to the technical field of laser diode patches, in particular to a fixing base for laser diode patches. Background technique [0002] At present, the principle of LD is to inject current into the semiconductor PN junction, realize the reverse distribution of particle number, generate stimulated radiation, and then use the positive feedback of the resonator to realize the laser oscillation generated by optical amplification. The laser diode has high efficiency and small size. , long life, but its output power is small (generally less than 2mW), poor linearity, and poor monochromaticity, so its application in cable TV systems is greatly limited, and it cannot transmit multi-channel, high-performance analog signals . [0003] The PD placement process uses an automatic placement machine. The PD pad and the chip are attached to the TO56 base according to the requirements set in the drawings through conductive silver glue (8280C), and t...
