Optical adapter and optical signal transmission device including same

摘要

An optical adapter includes a loading plate and a coupling lens. The coupling lens includes a main body, a first optical reflector, and a second optical reflector. The first optical reflector is positioned on the loading plate. The main body includes a top plate made of transparent material and spaced a predetermined distance from the loading plate. The second optical reflector is positioned on the first top plate. The first loading plate loads a portion of a planar optical waveguide of an optical printed circuit board. An optical signal from the planar optical waveguide is reflected by the first optical reflector to the second optical reflector, then is reflected by the second optical reflector to the outside of the optical adapter.

1. An optical adapter, comprising:
a first loading plate configured for loading a first portion of a planar optical waveguide of an optical printed circuit board (OPCB); and a first coupling lens comprising:
a first main body comprising a first top plate made of transparent material, the first top plate spaced a determined distance from the first loading plate, the first top plate comprising a first inner surface facing the first loading plate;a first optical reflector positioned on the first loading plate;a second optical reflector embedded in the first top plate; anda first converging lens positioned on the first inner surface; wherein optical signals from the planar optical waveguide are reflected by the first optical reflector to the second optical reflector, then reflected by the second optical reflector, and finally transmitted by the first top plate to the outside of the optical adapter.
