Optical communication device

摘要

An optical communication device includes a printed circuit board (PCB), a light emitting element, a light receiving element, and a light waveguide. The PCB includes a substrate. The substrate includes a first end surface and a second end surface opposite to the first end surface. The light emitting element is electrically connected to the first end surface. The light receiving element is electrically connected to the second end surface. The light waveguide includes a light incident end and a light emergent end. The light waveguide is embedded in the substrate. The light incident end is exposed to the first end surface and optically aligned with the light emitting element along a transmitting direction of the light waveguide. The light emergent end is exposed to the second end surface and optically aligned with the light receiving element along the transmitting direction of the light waveguide.
