Abstract: An integrated optical transceiver apparatus and an OLT are provided. A first splitter and a second splitter are integrated into a PLC structure of the apparatus. The first splitter is configured to output signal light of a first wavelength and signal light of a second wavelength, and output signal light of a third wavelength and signal light of a fourth wavelength. The second splitter is configured to separate the signal light of the third wavelength and the signal light of the fourth wavelength, output the signal light of the third wavelength, and output the signal light of the fourth wavelength. A first optical detector and a second optical detector are disposed on the PLC structure, where the first optical detector and the second optical detector are configured to convert, into electrical signals, the signal light output by the second splitter and the signal light output by the second splitter.

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.
