1. An optical-path-displacement-compensation-based emission optical power stabilization assembly, wherein the assembly comprises a laser, a lens and an optical fiber coupling port,
the laser, the lens, and the optical fiber coupling port being set 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;
the arrangement scheme enabling an initial distance between the laser and the lens, an initial distance between the lens and the optical fiber coupling port, and/or an initial distance between the laser and the optical fiber coupling port to deviate respective optimal coupling distances from an optimal coupling point for a preset value; and
the arrangement scheme enabling one or more objects among the laser, the lens, and the optical fiber coupling port which are fixed on the second substrate to generate an offset along with an elongation action of the second substrate when a working temperature of the emission optical power stabilization assembly increases, and the offset is used to compensate the preset value, so that the laser, the lens, and/or the optical fiber coupling port are close to the optimal coupling point.
