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: 9658396Abstract: Described herein are an apparatus, system, and method for providing a vertical optical coupler (VOC) for planar photonics circuits such as photonics circuits fabricated on silicon-on-insulator (SOI) wafers. In one embodiment, the VOC comprises a waveguide made from a material having refractive index in a range of 1.45 to 3.45, the waveguide comprising: a first end configured to reflect light nearly vertical by total internal reflection between the waveguide and another medium, a second end to receive the light for reflection, and a third end to output the reflected light. The VOC couples with a Si waveguide having a first region including: a first end to receive light; and an inverted tapered end in the direction of light propagation to output the received light, wherein the inverted tapered end of the Si waveguide is positioned inside the waveguide.Type: GrantFiled: September 29, 2011Date of Patent: May 23, 2017Assignee: Intel CorporationInventors: Haisheng Rong, Ofir Gan, Pradeep Srinivasan, Assia Barkai, I-Wei Andy Hsieh, Mahesh Krishnamurthi, Yun-Chung Neil Na

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
