    Abstract: An integrated circuit optical interconnect for connecting a first circuit part arranged to output an optical signal and a second circuit part arranged to receive an optical signal. The integrated circuit optical interconnect comprises a body comprising a glass material. The glass material has embedded therein an optical waveguide arrangement having an input, located at a surface of the body, for coupling to the first circuit part, and an output, located at a surface of the body, for coupling to the second circuit part. The optical waveguide arrangement comprises at least two optical waveguide segments extending in different directions through the glass material and at least one reflecting part arranged between the two optical waveguide segments, for directing an optical signal from one of the optical waveguide segments to the other of the optical waveguide segments. The optical waveguide arrangement is arranged to optically couple the input and the output, whereby an optical signal can pass from the input to the output through the optical waveguide arrangement. There is also provided an integrated circuit module comprising the integrated circuit optical interconnect, and a telecommunications switch comprising the integrated circuit module. There is further provided a method for manufacturing an integrated circuit optical interconnect.

    Abstract: A housing (11) for packaging an optical transmitter module and an optical transmitter module including the housing (11) are disclosed. The housing (11) includes: a body (111), a focusing structure (112), a first three-dimensional (3D) optical waveguide (113), and an optical fiber interface (114). The optical fiber interface (114) is located inside the body (111) and configured to accommodate a single-mode optical fiber (14). The first 3D optical waveguide (113) is embedded in the body (111). The focusing structure (112) is configured to: receive a first single-mode optical signal transmitted by a single-mode laser (13), and enable the received first single-mode optical signal to be focused for a first time at a focal point of the focusing structure (112). The first 3D optical waveguide (113) is configured to: receive the first single-mode optical signal that has been focused for the first time, and output the first single-mode optical signal that has been focused for the first time to the single-mode optical fiber (14). The focal point of the focusing structure (112) coincides with an input end of the first 3D optical waveguide (113). The housing (11) can be adapted to the single-mode optical fiber (14) for single-mode optical signal transmission.

    Abstract: This optical receptacle has a first optical surface, a reflection surface, a second optical surface, a light separation part, and a third optical surface. On the first optical surface, light from a photoelectric conversion element is incident. The reflection surface reflects the light incident on the first optical surface. The second optical surface allows the light reflected by the reflection surface to be emitted toward an end surface of an optical transmission body. The light separation part separates the light reflected by the reflection surface, into monitor light and signal light. The third optical surface allows the monitor light to be emitted toward a detection element. The light separation part includes divided reflection surfaces and divided transmission surfaces. At least one of the divided transmission surfaces includes one or more widened portions each having a width larger than those of the other divided transmission surfaces.

    Abstract: Methods and systems for grating couplers incorporating perturbed waveguides are disclosed and may include in a semiconductor photonics die, communicating optical signals into and/or out of the die utilizing a grating coupler on the die, where the grating coupler comprises perturbed waveguides. The perturbed waveguides may comprise a variable width along their length. The grating coupler may comprise a single polarization grating coupler comprising perturbed waveguides and a non-perturbed grating. The grating coupler may comprise a polarization splitting grating coupler (PSGC) that includes two sets of perturbed waveguides at a non-zero angle, or a plurality of non-linear rows of discrete shapes. The PSGC may comprise discrete scatterers at an intersection of the sets of perturbed waveguides. The grating couplers may be etched in a silicon layer on the semiconductor photonics die or deposited on the semiconductor photonics die. The grating coupler may comprise individual scatterers between the perturbed waveguides.

    Abstract: A single-core bidirectional optical communication module and a single-core bidirectional optical communication connector are provided which can decrease in size without greatly changing the structure of the past optical connector housing. An optical communication module 1 includes an optical transceiver circuit unit 21 in which a light-emitting element and a light-receiving element are arranged in parallel and an optical path changing component 25 having a structure in which the attachment and detachment direction of an optical fiber cable is perpendicular to the optical transceiver circuit unit 21. An optical communication connector 2 includes a single-core bidirectional optical communication module 1 and an optical connector housing 3 that houses the single-core bidirectional optical communication module 1 so that the optical axis of the optical fiber cable is perpendicular to the optical transceiver circuit unit 21.
