Patent number: 9709734Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for an optical coupler. In some embodiments, the device may include an optical waveguide to transmit light input from a light source. The optical waveguide may include a semiconductor layer, having a trench with one facet that comprises an edge formed under an approximately 45 degree angle and another facet formed substantially normal to the semiconductor layer. The edge may interface with another medium to form a mirror to receive inputted light and reflect received light substantially perpendicularly to propagate the received light. Other embodiments may be described and/or claimed.Type: GrantFiled: March 30, 2016Date of Patent: July 18, 2017Assignee: Intel CorporationInventors: Mahesh Krishnamurthi, Judson Ryckman, Haisheng Rong, Ling Liao, Harel Frish, Oshrit Harel, Assia Barkai, Yun-Chung Na, Han-Din Liu

Patent number: 9395494Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for an optical device having a semiconductor layer to propagate light and a mirror disposed inside the semiconductor layer and having echelle grating reflective surface to substantially totally internally reflect the propagating light inputted by one or more input waveguides, to be received by one or more output waveguides. The waveguides may be disposed in the semiconductor layer under a determined angle relative to the mirror reflective surface. The determined angle may be equal to or greater than a total internal reflection angle corresponding to the interface, to provide substantially total internal reflection of light by the mirror. The mirror may be formed by an interface of the semiconductor layer comprising the mirror reflective surface and another medium filling the mirror, such as a dielectric. Other embodiments may be described and/or claimed.Type: GrantFiled: December 16, 2015Date of Patent: July 19, 2016Assignee: Intel CorporationInventors: Mahesh Krishnamurthi, I-Wei Hsieh, Haisheng Rong, Oshrit Harel, Harel Frish, Assia Barkai, Wenhua Lin
