Abstract: Various embodiments for an optical system are described herein. Generally, the optical system may include an optical transmitter coupled to an optical signal transmission path, an optical receiver coupled to an optical signal reception path, and an external signal path extending between an external optical assembly and both the optical signal transmission path and the optical signal reception path. An optical polarization division multiplexer may be provided to couple the optical signal transmission path and the optical signal reception path to the external signal path. A first non-reciprocal polarization rotator may be also positioned along the external signal path between the optical polarization division multiplexer and the external optical assembly. Further, a quarter wave plate may be positioned along the external signal path between the non-reciprocal polarization rotator and the external optical assembly.

Abstract: A spectrometer and method for determining an emitted light spectrum. An input light signal is received and directed to an array of interferometers using waveguides. A plurality of self-interfering signals are detected from a first plurality of interferometers in the array of interferometers. The first plurality of interferometers has fewer interferometers than required to satisfy the Nyquist criterion for reconstructing the emitted light spectrum. The emitted light spectrum is reconstructed from the plurality of self-interfering signals using compressive sensing. The plurality of self-interfering signals can provide an interference pattern used to reconstruct the emitted light spectrum. A second plurality of interferometers may output a second plurality of self-interfering signals to reconstruct a low resolution spectrum of the input light signal satisfying the Nyquist criterion. Low resolution signal components can be detected from the low resolution spectrum and used to pre-process the interference pattern.

Abstract: A microwave switch for transmitting signals having a plurality of ports and a plurality of signal paths for selective transmission of the signals. Each signal path is disposed between a respective pair of the ports and each signal path has a conducting state in which signal transmission occurs between the respective pair of ports and a non-conducting state in which signal transmission does not occur between the respective pair of ports. The switch also has a plurality of actuators, each actuator being adapted to actuate at least one of the signal paths between the conducting and non-conducting states. At least one of the ports and at least one of the signal paths are located on a first plane and the remainder of the ports and the signal paths are located on a second plane such that there are no cross over points between the signal paths in any of the planes. A switch matrix can be built using this bi-planar switch such that the switches in the matrix are connected without any cross over points.

Abstract: A waveguide assembly for operation over a range of temperatures includes a waveguide body and a plurality of restraining strips coupled to the waveguide body. The waveguide body includes a pre-curved narrow sidewall of material having a first coefficient of thermal expansion (CTE). The restraining strips are coupled to the waveguide body at first and second lateral points on either side of the pre-curved narrow sidewall laterally and are spaced apart along the length of the waveguide body, and are made from a material having a second CTE much less than the first CTE. Thus, when the temperature of the waveguide assembly changes, the restraining strips maintain a substantially constant lateral distance between said first and second lateral points over the range of temperatures such that as the length of the waveguide varies with temperature, the curvature of the pre-curved narrow sidewall also changes, causing the effective large dimension of the waveguide assembly to vary such that the combination of said changes results in a constant phase length for said waveguide body.

Abstract: A high power high temperature superconductive circuit for use in various microwave devices including filters, dielectric resonator filters, multiplexers, transmission lines, delay lines, hybrids and beam-forming networks has thin gold films deposited either on a substrate or on top of the high temperature superconductive film. Alternatively, other metal films can be used or a plurality of dielectric films can be used or a dielectric constant gradient substrate can be used. The use of these materials in a part or parts of a microwave circuit reduces the current density in those parts compared to the level of current density if only high temperature superconductive film is used. This increases the power handling capability of the circuit.
