Abstract: A self-calibrating transceiver includes a set of digital to analog converters configured to process a comb calibration waveform, at least one IQ modulator configured to generate at least one optical signal comprising I and Q components operably coupled from the set of digital to analog converters. A receiver photonics circuit is configured to convert the coupled optical signals to electrical signals. The receiver photonics circuit includes a set of analog to digital converters coupled to convert the electrical signals to digital signals representative of the comb calibration waveform in cartesian IQ format. Processing circuitry is coupled to determine at least magnitude and/or phase of the digital signals and generate filter coefficients based on a comparison of at least magnitude and/or phase to the comb calibration waveform.

Abstract: A method for calibrating an optical transceiver. The method can include configuring optical switches to enable routing at least one output signal of modulator circuitry operably coupled to a first receive path of a coherent optical transceiver. The method can include configuring the input to at least one modulator to generate at least one first stimulus signal. The method can include configuring a path from the first receiver analog-to-digital converter to an adaptive algorithm circuitry. The method can include adapting at least one bias setting of a photodiode associated with the first receiver in response to at least one first stimulus detected at the first receiver analog-to-digital converter to an adaptive algorithm circuitry. The method can include determining an optimum value of a photodiode associated with the first receiver.

Abstract: Elements formed from magnetic materials and their methods of manufacture are presented. Magnetic materials include a magnetic alloy material, such as, for example, an Fe-Co alloy material (e.g., the Fe-Co-V alloy Hiperco-50(R)). The magnetic alloy materials may comprise a powdered material suitable for use in additive manufacturing techniques, such as, for example direct energy deposition or laser powder bed fusion. Manufacturing techniques include the use of variable deposition time and energy to control the magnetic and structural properties of the materials by altering the microstructure and residual stresses within the material. Manufacturing techniques also include post deposition processing, such as, for example, machining and heat treating. Heat treating may include a multi-step process during which the material is heated, held and then cooled in a series of controlled steps such that a specific history of stored internal energy is created within the material.

Abstract: A quench cooler or transferline heat exchanger for quenching the effluent from a thermal cracking furnace has an inlet connector between the cracking furnace tubes and the tubes of the quench cooler. The tubes of the quench cooler are arranged in a circular pattern of spaced tubes. The flow passage of the connector is configured to initially decelerate and then re-accelerate the gas. This involves a conical diverging diffuser followed by a radial diffuser and then an annular converging section. The cross sectional transitions are smooth to avoid dead spaces and minimize pressure loss.
