Description

Technical Field

[0001] The utility model relates to the technical field of diode power testing, in particular to a laser diode power testing device. Background Art

[0002] Laser diode is essentially a semiconductor diode. According to whether the PN junction material is the same, laser diode can be divided into homojunction, single heterojunction (SH), double heterojunction (DH) and quantum well (QW) laser diode. Quantum well laser diode has the advantages of low threshold current and high output power, and is the mainstream product in the current market. Compared with lasers, laser diodes have the advantages of high efficiency, small size and long life, but their output power is small (generally less than 2mW), poor linearity and monochromaticity are not very good, which greatly limits their application in cable TV systems and cannot transmit multi-channel, high-performance analog signals. In the return module of a bidirectional optical receiver, quantum well laser diodes are generally used as light sources for uplink transmission. When the laser diode injection current is below the critical current density, the luminescence mechanism is mainly spontaneous radiation, the spectrum is widely dispersed, and the bandwidth is approximately between 100 and 500 angstroms.

This testing method requires people to align the positive and negative test columns with the positive and negative terminals on the laser diode every time they test a laser diode, resulting in reduced test efficiency.
