Lens component, optical multiplexing/demultiplexing module, and method for manufacturing optical multiplexing/demultiplexing module

A lens component comprising:

• a prism including a first surface, a second surface obliquely facing the first surface, a third surface extending in a direction that intersects with the first surface and obliquely facing the second surface, and a first side surface and a second side surface connecting the first surface and the second surface to each other and facing each other;
• and
• a plurality of GRIN lenses arranged in the prism such that each lens extends from the first surface toward the second surface,
• wherein each of the plurality of GRIN lenses has a first end that is exposed at the first surface,
• wherein the lens component is configured such that light input to the first end of each of the plurality of GRIN lenses is reflected by the second surface and is emitted from the third surface, or light input from the third surface and reflected by the second surface or light input to the second surface is emitted from the first end of each of the plurality of GRIN lenses, and
• wherein the first side surface and the second side surface of the prism include a curved surface shape.
