  • Patent number: 11424401
    Abstract: The present invention relates to a plurality of phononic devices and a method of manufacturing thereof. In one embodiment, highly sensitive superconducting cryogenic detectors integrate phononic crystals into their architecture. The phononic structures are designed to reduce the loss of athermal phonons, resulting in lower noise and higher sensitivity detectors. This fabrication process increases the qp generation recombination rate, thus, reducing the noise equivalent power (NEP) without sacrificing the scalability. A plurality of phononic devices, such as a kinetic inductance detector (KID), a transition edge sensor (TES) bolometer, and quarterwave backshort, can be manufactured according to the methods of the present invention.

  • Patent number: 11340392
    Abstract: The present invention relates to electromagnetic meta-material structures to serve as linear polarization sensitive mirrors. Two distinct classes have been developed, including: 1) a phase cohering reflector which maintains the phase of both polarization states with a controlled delay between polarization states, and 2) a phase de-cohering reflector which preserves the phase of one polarization state and destroys the coherence in the other. These reflective structures enable mitigation of spurious resonances in dual-polarization optical systems and phase compensation between polarization states. These polarization control structures have applications in absorber coupled detectors and receiver systems for space-borne and sub-orbital remote sensing applications.

  • Patent number: 11313729
    Abstract: The present invention relates to a phononic-isolated Kinetic Inductance Detector (KID) and a method of fabrication thereof. The KID is a highly sensitive superconducting cryogenic detector which can be scaled to very large format arrays. The fabrication process of the KID of the present invention integrates a phononic crystal into a KID architecture. The phononic structures are designed to reduce the loss of recombination and athermal phonons, resulting in lower noise and higher sensitivity detectors.

  • Publication number: 20070262835
    Abstract: A microwave waveguide filter comprises an input waveguide section; an output waveguide section; a plurality of resonator sections disposed between the input and output waveguide sections; and a plurality of coupling sections disposed on either side of each of the resonator sections; wherein the input waveguide section, the resonator sections, and the output waveguide section have at least four fold symmetric quadruple ridge cross-sections and the coupling sections have at least four fold symmetric cross-sections.

  • Publication number: 20070146723
    Abstract: A signal conditioning module provides a polarimeter capability in a photometric system. The module may include multiple variable delay polarization modulators. Each modulator may include an input port, and a first arm formed to include a first reflector and first rooftop mirror arranged in opposed relationship. The first reflector may direct an input radiation signal to the first rooftop mirror. Each modulator also may include an output port and a second arm formed to include a second reflector and second rooftop mirror arranged in opposed relationship. The second reflector can guide a signal from the second rooftop mirror towards the output port to provide an output radiation signal. A beamsplitting grid may be placed between the first reflector and the first rooftop mirror, and also between the second reflector and the second rooftop mirror. A translation apparatus can provide adjustment relative to optical path length vis-a-vis the first arm, the second arm and the grid.
