Abstract: Examples herein relate to optical modules. In particular, implementations herein relate to optical modules that include top-emitting VCSELs and/or top-entry photodetectors. The optical modules include a first interposer having opposing first and second sides and a second interposer having opposing first and second sides. The optical modules include a plurality of top-emitting vertical-cavity surface-emitting lasers (VCSELs) coupled to the second interposer and a plurality of electrical conductors forming electrical paths between electrical contacts of the top-emitting VCSELs and the second side of the second interposer.

Abstract: Systems and methods are provided for a dual-side bi-directional optical multiplexing system includes a light receiving elements array receiving light from in an egress propagation direction from an optical fiber, arranged at a side of the optical fiber. The system also includes a light transmitting elements array emitting light in an ingress propagation direction into the optical fiber, and arranged at a second position to an opposing side of the optical fiber. The light receiving elements array and the light transmitting elements array are on dual-sides of the system with respect to the optical fiber. The system also includes bi-directional micro-optics interfacing with the optical fiber, and interfacing with the light transmitting elements array to direct light propagating in the ingress direction emitted from the light transmitting element array towards the optical fiber.

Abstract: Examples herein relate to optical modules. In particular, implementations herein relate to optical modules that include top-emitting VCSELs and/or top-entry photodetectors. The optical modules include a substrate having opposing first and second sides. The optical modules further includes a first interposer having opposing first and second sides and a plurality of top-emitting vertical-cavity surface-emitting lasers (VCSELs). The VCSELs are flip-chipped to the second side of the first interposer such that they are disposed between the substrate and the first interposer. The VCSELs are configured to emit optical signals having different wavelengths. The optical signals are configured to be combined and transmitted over a single optical fiber. The optical modules include a plurality of electrical conductors forming electrical paths between electrical contacts of the top-emitting VCSELs and the substrate.

Abstract: An example method of manufacturing an optical interface. An optical socket may be provided that has an alignment feature that is to engage an optical connector, and first solder attachment pads. A printed circuit board may be provided that has an active optical device and second solder attachment pads. The optical socket may be connected to the printed circuit board by reflowing solder between the first and second solder attachment pads. The first and second solder attachment pads, the alignment feature, and the active optical device are positioned such that, while reflowing the solder, the solder automatically forces the optical socket into an aligned position.

Abstract: In the examples provided herein, a system includes a loop waveguide; and a grating coupler formed on the loop waveguide to couple light impinging on the grating coupler having a first polarization into the loop waveguide in a first direction, and to couple light having a second polarization, orthogonal to the first polarization, into the loop waveguide in a second direction. The system also includes a ring resonator positioned near the loop waveguide tuned to have a resonant wavelength at a first wavelength to couple light at the first wavelength out of the loop waveguide into the ring resonator. An output waveguide positioned near the ring resonator couples light out of the ring resonator into the output waveguide; and a photodetector detects light propagating out of a first end and a second end of the output waveguide.

Abstract: In example implementations, an optical connector is provided. The optical connector includes a jumper holder, a base bracket, and an optical ferrule. The jumper holder holds a plurality of ribbon fibers. The base bracket is coupled to an electrical substrate to mate with the jumper holder. The optical ferrule is coupled to an end of each one of the plurality of ribbon fibers. The optical ferrule is laterally inserted into a corresponding orthogonal socket that is coupled to a silicon interposer on the electrical substrate to optically mate the optical ferrule to the orthogonal socket.

Abstract: An apparatus (2) can comprise an optical slab (4) comprising a rigid substrate of substantially transmissive material. The apparatus (2) can also comprise a WDM multiplexer (6) to receive and combine a plurality of optical signals (14, 16 and 20) at different wavelengths to form a combined optical signal (24) in the optical slab (4) having an aggregate power. The apparatus can further comprise a broadcaster (28) to distribute the combined optical signal (24) from the optical slab (4) to each of a plurality of different optical receivers (30, 32 and 34) with a fraction of the aggregate power of the combined optical signal (24).
