摘要： 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.

摘要： A wafer scale implementation of an opto-electronic transceiver assembly process utilizes a silicon wafer as an optical reference plane and platform upon which all necessary optical and electronic components are simultaneously assembled for a plurality of separate transceiver modules. In particular, a silicon wafer is utilized as a "platform" (interposer) upon which all of the components for a multiple number of transceiver modules are mounted or integrated, with the top surface of the silicon interposer used as a reference plane for defining the optical signal path between separate optical components. Indeed, by using a single silicon wafer as the platform for a large number of separate transceiver modules, one is able to use a wafer scale assembly process, as well as optical alignment and testing of these modules.

摘要： A configuration for routing electrical signals between a conventional electronic integrated circuit (IC) and an opto-electronic subassembly is formed as an array of signal paths carrying oppositely-signed signals on adjacent paths to lower the inductance associated with the connection between the IC and the opto-electronic subassembly. The array of signal paths can take the form of an array of wirebonds between the IC and the subassembly, an array of conductive traces formed on the opto-electronic subassembly, or both.

摘要： An opto-electronic assembly is provided comprising a substrate (generally of silicon or glass) for supporting a plurality of interconnected optical and electrical components. A layer of sealing material is disposed to outline a defined peripheral area of the substrate. A molded glass lid is disposed over and bonded to the substrate, where the molded glass lid is configured to create a footprint that matches the defined peripheral area of the substrate. The bottom surface of the molded glass lid includes a layer of bonding material that contacts the substrate's layer of sealing material upon contact, creating a bonded assembly. In one form, a wafer level assembly process is proposed where multiple opto-electronic assemblies are disposed on a silicon wafer and multiple glass lids are molded in a single sheet of glass that is thereafter bonded to the silicon wafer.

摘要： An optical modulator is formed to include a plurality of separate electrodes disposed along one arm, the electrodes having different lengths and driven with different signals to provide for multi-level signaling (e.g., PAM-4 signaling). By using separate drivers to energize the different sections, the number of sections energized at a given point in time will define the net phase shift introduced to the optical signal. The total length of the combined modulator sections is associated with a π phase shift (180°). Each section is driven by either a digital "one" or "zero", so as to create the multi-level modulation. An essentially equal change in power between adjacent transmitted symbols is accomplished by properly adjusting the lengths of each individual section.

摘要： An electronic dispersion compensation (EDC) arrangement for a multi-channel optical receive utilizes a time division technique to "share" a common adaptive algorithm block between a plurality of N separate channels. The algorithm block embodies a specific algorithm associated with correcting/updating tap weights for the delay lines forming the equalizing elements, and a time slot assignment element is used in conjunction with the algorithm block to control the access of the various channels to the algorithm block. In situations where certain channels experience a greater degree of dispersion than others, the time slot assignment element may be configured to allot a greater number of time slots to the affected channels.

摘要： Computer-aided design (CAD) tools are used to perform the integrated design, verification and layout of electrical and optical components in a monolithic, silicon-based electro-optic chip. Separate top-level behavioral logic designs are prepared for the three different types of elements included within the final, silicon-based monolithic structure: 1) digital electronic integrated circuit elements (12); 2) analog/mixed signal electronic integrated circuit elements (14); and 3) opto-electronic elements (16) (including passive and active optical elements). Once the behavioral logic design is completed, the results are combined and co-simulated (18). physical layout design is developed and verified for each different type of element in the circuit. The separate physical layouts are then co-verified (26), to assess the properties of the overall physical design. The results of the co-simulation (18) are compared to t results of the co-verification (26), with alterations made in the logic design and/or the physical layout until the desired operating parameters are obtained. Once the desired results are generated, conventional wafer-level fabrication operations are then considere to provide a final product ("tape out").

摘要： An HDMl 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.
