Abstract
An optical element includes a substrate, a first insulating layer, a first optical waveguide layer, a first edge coupler, and a first micro-optical element. The first insulating layer is disposed on the substrate. The first optical waveguide layer is disposed on the first insulating layer to transmit a light beam. The first edge coupler is disposed on the first insulating layer and coupled to an end of the first optical waveguide layer. The first micro-optical element is disposed on the substrate and includes a first inclined surface. The first micro-optical element is located within a first groove formed between the substrate, the first insulating layer, the first optical waveguide layer, and the first edge coupler. The light beam is sequentially transmitted from the first optical waveguide layer to the first edge coupler, emitted from the first edge coupler, and reflected by the first inclined surface to an optical fiber connector.
