High-coupling-efficiency photoelectric coupler based on bowl-shaped and super-lens structures

The invention relates to a high-coupling-efficiency photoelectric coupler based on a bowl-shaped and super-lens structure, and the coupler comprises an upper frame which is provided with a recessed part; the light emitting unit is mounted in the concave part; the high light transmittance silica gel is covered on the surface of the light emitting unit; a lower frame, wherein a slide holder is arranged on the lower frame; and the receiving unit is arranged on the slide holder. According to the high-coupling-efficiency photoelectric coupler based on the bowl-shaped and super-lens structures, light beams emitted by a light source can be reflected, converged and guided to a corresponding light receiver, scattering and reflection losses in the light beam propagation process are reduced, and through unique optical design and material selection, the coupling efficiency is improved; and the coupling efficiency of light energy from the luminous source to the light receiver is effectively improved. 本发明涉及基于碗状和超透镜结构的高耦合效率
