摘要： A multicast exchange optical switch includes an input port device including M input ports, an output port device including N output ports, a diffractive beam splitter, an optical focusing component, and a 1×N array of reflective devices. The diffractive beam splitter diffracts each input signal beam from the input ports into at least N directions. The optical focusing component includes a first focusing lens and a second focusing lens. The first focusing lens focuses sub-beams from the respective input ports along the Y-axis direction having the same diffraction order. The second focusing lens focuses on the X-axis direction sub-beams from the same input port having different diffraction orders. The 1×N array of reflective devices is provided at the focal plane of the optical focusing component and each reflective device reflects a sub-beam from any one of the input ports to any one of the output ports.

摘要： 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.
