An optical subassembly structure for mode conversion by an active alignment of an optical fiber with a semiconductor optical waveguide includes a sub-mount for holding the optical subassembly structure, a semiconductor die mounting on the sub-mount, the semiconductor optical waveguide growing on the semiconductor die and a glass capillary subassembly actively aligned to the semiconductor optical waveguide.

Optical subassembly structure

An optical interposer for providing optimal optical coupling between an optical transceiver interface and an external optical interface includes an interposer photonic integrated circuit (PIC) operably configured to couple an optical signal between the optical transceiver interface and the external optical interface, one or more waveguide based optical devices operably integrated on a common substrate and one or more of interposer input/output (I/O) channels operably configured with the optical transceiver interface and the external optical interface.

Optical interposer for optical transceiver

An optical mode converter for coupling between photonic integrated circuit (PIC) and optical fiber of different mode sizes is illustrated. The optical mode converter includes a waveguide assembly including a Single waveguide structure, a Multi-layer waveguide structure, and a Transitional waveguide structure. The Single waveguide structure includes a single waveguide. The dimension and propagation constant of a first end, of the single waveguide, is similar to a waveguide of a photonic integrated circuit (PIC). Furthermore, the Multi-layer waveguide structure included a multi-layer waveguide. Further, the Transitional waveguide structure is formed at a transitional structure. The Transitional waveguide structure allows transition of an optical mode between the Single waveguide structure and Multi-layer waveguide structure. The Multi-layer waveguide structure is configured for coupling light between the Transitional waveguide structure and an optical fiber and the Single waveguide structure is configured for coupling the light between the PIC and the Transitional waveguide structure.
