  • Publication number: 20230044483
    Abstract: A method of decomposing a cured aromatic epoxy resin uses a molten salt bath at less than about 350° C. The molten salt bath includes a plurality of alkali metal hydroxides. The cured aromatic epoxy resin can be in intimate physical contact with a metal or alloy. The cured aromatic epoxy resin can be patterned by a lithographic method. The lithographic method can be multibeam interference lithography to form a three-dimensional photonic crystal template on a conductive substrate for electrodeposition of metal. Contacting the three-dimensional photonic crystal template with the electrodeposited metal with the molten salt bath can form a metal matrix device displaying a periodic pattern that is the inverse of the periodic pattern of the decomposed three-dimensional photonic crystal template.

  • Publication number: 20230044343
    Abstract: A method to form a three-dimensional photonic crystal template with a gradient structure involves irradiating a photoresist composition of a thickness of at least 15 ?m from at least four laser beams to yield a periodic patterned with a percolating matrix of mass in constructive volumes of a cured photoresist composition and destructive volumes of voids free of condensed matter where the proportion of constructive volume displays a gradient from the irradiated surface to the substrate after development. For a given light intensity, photoinitiator concentration in the photoresist composition, and a given thickness, by irradiating for a relatively short period, a three-dimensional photonic crystal template displaying a gradient having greater constructive volume proximal the air interface forms and a relatively long irradiation period results in a gradient having greater constructive volume proximal the substrate.

  • Publication number: 20230042586
    Abstract: A three-dimensional photonic crystal template on a reflective substrate displays a periodic patterned from multibeam interference lithography with constructive volumes of a cured photoresist composition and destructive volumes that are voids free of mass containing defects and where the reflective substrate is conductive. A method to generate the three-dimensional photonic crystal template includes using at least four laser beams of unequal intensity, oriented such that a dose of light controlled by the irradiation time generates the periodic pattern with a small dose, where the light reflected from the substrate is insufficient to activate a threshold quantity of photoinitiator in the destructive volumes for the formation of any anomalous condensed matter in the intended void volume.

  • Patent number: 11533255
    Abstract: In order to enable dynamic scaling of network services at the edge, novel systems and methods are provided to enable addition of add new nodes or removal of existing nodes while retaining the affinity of the flows through the stateful services. The methods provide a cluster of network nodes that can be dynamically resized to handle and process network traffic that utilizes stateful network services. The existing traffic flows through the edge continue to function during and after the changes to membership of the cluster. All nodes in the cluster operate in active-active mode, i.e., they are receiving and processing traffic flows, thereby maximizing the utilization of the available processing power.

  • Publication number: 20220349746
    Abstract: An optical detector module can be used to implement proximity sensing function by detecting ambient light outside of the optical detector module in accordance with a first detection threshold. An optical detector module can be further used to implement other active functions such as material detection (e.g., skin) or depth-sensing by emitting one or more optical signals (e.g., light pulses at a specific wavelength) and detecting the reflected optical signals relative to a second and/or third detection threshold. The disclosure provides technical solutions for actively monitoring detection threshold(s) of an optical detector module to achieve better power management. In some embodiments, such solutions are useful for photodetectors having a wide sensing bandwidth, such as a photodetector formed in germanium or a photodetector comprising an absorption region comprising germanium.
