Abstract: 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.

Abstract: 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.

Abstract: Silicon photonic integrated circuit (PIC) on a multi-zone semiconductor on insulator (SOI) substrate having at least a first zone and a second zone. Various optical devices of the PIC may be located above certain substrate zones that are most suitable. A first length of a photonic waveguide structure comprises the crystalline silicon and is within the first zone, while a second length of the waveguide structure is within the second zone. Within a first zone, the crystalline silicon layer is spaced apart from an underlying substrate material by a first thickness of dielectric material. Within the second zone, the crystalline silicon layer is spaced apart from the underlying substrate material by a second thickness of the dielectric material.

Abstract: Optical receiver packages and device assemblies that include photodetector (PD) chips having focus lenses monolithically integrated on PD die backsides are disclosed. An example receiver package includes a support structure, a PD die, and an optical input device. The PD die includes a PD, integrated proximate to a first face of the PD die, and further includes a lens, integrated on, or proximate to, an opposite second face. The first face of the PD die faces the support structure, while the second face (“backside”) faces the optical input device. The optical receiver architectures described herein may provide an improvement for the optical alignment tolerance issues, especially for high-speed operation in which the active aperture of the PD may have to be very small. Furthermore, architectures described herein advantageously enable integrating a focus lens in a PD die that may be coupled to the support structure in a flip-chip arrangement.

Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for an optical coupler including an optical waveguide to guide light to an optical fiber. In embodiments, the optical waveguide includes a tapered segment to propagate the received light to the optical fiber. In embodiments, the tapered segment is buried below a surface of a semiconductor substrate to transition the received light within the semiconductor substrate from a first optical mode to a second optical mode to reduce a loss of light during propagation of the received light from the optical waveguide to the optical fiber. In embodiments, the surface of the semiconductor substrate comprises a bottom planar surface of a silicon photonic chip that includes at least one or more of passive or active photonic components. Other embodiments may be described and/or claimed.
