    Abstract: An optical coupler (1600) comprising a fiber optic structure has a portion of an outer surface (1634) that extends in a longitudinal direction of the fiber optic structure. The longitudinal outer surface portion (1634) may be optically coupled with a waveguide core (1668) of an optical integrated circuit (1604). The fiber optic structure may also include a second outer surface that extends transverse to the longitudinal direction of the fiber optic structure. The fiber optic structure may also include a third outer surface portion (1637) that is butt coupled to an end of an optical fiber (1608) to optically couple the third outer surface (1637) portion with the optical fiber (1608).

    Abstract: Embodiments described herein describe a sub-mount that is etched to include respective cavities with at least two adjacent sides that align optical filters and a mirror. Moreover, the cavities are arranged on the sub-mount such that when the filters and mirror are disposed in the cavities, they align in a manner that enables the performance of a multiplexing or demultiplexing function as part of, for example, a zigzag multiplexer/demultiplexer. In one embodiment, the filters and mirrors are aligned passively rather than actively. The sub-mount may then be placed on a substrate that includes other components of a ROSA or TOSA. In one embodiment, the substrate is also etched to include a cavity two adjacent sides to align the sub-mount so that sub-mount is passively aligned once disposed into the cavity.

    Abstract: An arrangement for providing passive alignment of optical components on a common substrate uses a set of reference cavities, where each optical device is positioned within a separate reference cavity. The reference cavities are formed to have a predetermined depth, with perimeters slightly larger than the footprint of their associated optical components. The reference cavity includes at least one right-angle corner that is used as a registration corner against which a right-angle corner of an associated optical component is positioned. The placement of each optical component in its own reference cavity allows for passive optical alignment to be achieved by placing each component against its predefined registration corner.

    Abstract: An optical modulator is configured to include multiple modulating sections formed along each arm and create a unary-encoded optical output signal by driving the number of sections required to represent the data value being transmitted (e.g., three sections driven to represent the data value "3", four sections driven to represent the data value "4"). An auxiliary modulating section, isolated from the optical signal path, is included for creating a path for current flow in situations where only an odd number of modulating sections are required to represent the data. The activation of the auxiliary modulation section minimizes the current imbalance that would otherwise be present along a common node of the arrangement.

    Abstract: An HDMI interconnect arrangement is presented that performs a pulse-amplitude modulation (PAM) conversion of the TMDS audio/video signals in order to simultaneously transmit all three channels over a single optical fiber. The set of three audio/video TMDS channels is applied as an input to a PAM-8 optical modulator, which functions to encode the set of three channels onto an optically-modulated output signal. The modulated optical signal is thereafter coupled into an optical fiber within an active HDMI cable and transmitted to an HDMI receiver (sink). The TMDS CLK signal is not included in this conversion into the optical domain, but remains as a separate electrical signal to be transmitted along a copper signal path within the active HDMI cable.
