Abstract
A spot size conversion apparatus and a related device are provided. The spot size conversion apparatus includes a vertical spot size converter. The vertical spot size converter includes N geometric waveguides. A space between any two adjacent geometric waveguides is filled with a filling material. Each of the N geometric waveguides includes an incident surface and an emergent surface. The refractive index of the filling material is less than the refractive indices of the two adjacent geometric waveguides. Geometric feature sizes between respective incident surfaces and respective emergent surfaces of the N geometric waveguides gradually decrease in a first direction. The vertical spot size converter is configured to receive a first electromagnetic wave signal, perform vertical spot size processing on the first electromagnetic wave signal using the N geometric waveguides, and output a second electromagnetic wave signal.
