Abstract: An apparatus includes an electrical connector. The electrical connector is configured to electrically couple a signal transmission line to another signal transmission line. The electrical connector includes a first electrical conductor and a second electrical conductor. The first electrical conductor is disposed around a center axis. The first electrical conductor is disposed azimuthally symmetric around the center axis. The second electrical conductor is disposed around the center axis and around the first electrical conductor. The second electrical conductor is disposed azimuthally symmetric around the center axis. Faces on opposing ends of the electrical connector along the center axis are configured to mate the signal transmission line and the second electrical conductor in a first plane and the other signal transmission line and the second electrical conductor in a second plane.

Abstract: A differential transmission line includes a sheath, a first conductive structure, a second conductive structure, and a resistive layer. The first conductive structure is disposed along the differential transmission line and within the sheath, and contributes to formation of a three-dimensional electromagnetic field. The second conductive structure is disposed along the differential transmission line and within the sheath, and contributes to formation of the three-dimensional electromagnetic field. The resistive layer is aligned to be substantially perpendicular to an electric field component of a first mode of the three-dimensional electromagnetic field, and to provide absorption of an electric field component of a second mode of the three-dimensional electromagnetic field.

Abstract: A coherent optical receiver includes a local oscillator (LO) laser configured to provide an LO signal. The LO laser includes a hybrid external cavity and an active gain medium within the hybrid external cavity, where the LO laser is defined between a first optical reflector on a chip including the active gain medium and a second optical reflector not on the chip.

Abstract: An apparatus for acquiring a desired response to an electromagnetic signal includes an adaptive network that receives a feedback signal and dynamically adjusts an electrical characteristic of the adaptive network in response to the feedback signal, the adaptive network electrically cooperating with an electrical component. A measurement device measures a parameter indicative of a combined response by the electrical component and the adaptive network to an impinging electromagnetic signal. A processor identifies, in accordance with the measured parameter, the feedback signal that reduces the difference between a predetermined response and the combined response to the electromagnetic signal. A feedback generator generates the identified feedback signal and conveys the generated feedback signal to the adaptive network.
