Abstract: An optical-path-displacement-compensation-based emission optical power stabilization assembly, comprising: a laser, a lens, and an optical fiber coupling port disposed on a first substrate and a second substrate according to a preset arrangement scheme, wherein an expansion coefficient of the second substrate is larger than that of the first substrate, and the preset arrangement scheme enables initial distances between the laser and the lens, between the lens and the optical fiber coupling port, and/or between the laser and the optical fiber coupling port to differ from respective optical coupling distances from an optical coupling point by a preset value, thereby ensuring that a coupling loss on an optical path changes along with the temperature, forming a complementary effect with respect to an optical power-temperature curve of the laser, which reduces a temperature-caused fluctuation of the emission optical power of an optical assembly.
