Description

technical field [0001] The application belongs to the technical field of optical communication, and in particular relates to an optical power monitoring component and an optical module. Background technique [0002] The optical module is composed of optoelectronic devices, functional circuits and optical ports. Among them, optoelectronic devices include two parts: emission and reception. To put it simply, the main function of the optical module is to realize photoelectric conversion. At the sending end, the electrical signal is converted into an optical signal. After transmission through the optical fiber, the optical signal is converted into an electrical signal at the receiving end, thereby realizing the transmission of information. [0003] In the optical module, it is usually necessary to adjust the optical power of the laser according to specific conditions, which requires monitoring the optical power of the laser first. In the optical power monitoring component of th...
