  • Publication number: 20230359879
    Abstract: A multipath deep diffractive neural network comprises a first optical path for performing a first task and a second optical path for performing a second task. The second task is different than the first task. The multipath deep diffractive neural network further comprises an overlap optical path where the first optical path and the second optical path overlap. The multipath deep diffractive neural network comprises one or more optical elements that are configured to create a multipath optical neural network that performs a plurality of different tasks using multi-task machine learning.

  • Publication number: 20210157211
    Abstract: The techniques described herein relate to methods and apparatus for interferometric modulation. An apparatus includes an interferometric device comprising a first optical path and a second optical path, and at least one Franz-Keldysh (FK) modulator disposed in either the first optical path or the second optical path of the interferometric device. The interferometric device receives input light, wherein a first portion of the input light travels along the first optical path of the interferometric device, and a second portion of the input light travels along the second optical path of the interferometric device. The FK modulator modulates an intensity of either the first portion of the input light or the second portion of the input light.

  • Publication number: 20170096339
    Abstract: A method for preparing a film of aligned rod-like nanostructures or nanotubes comprises preparing a solution that comprises rod-like nanostructures or nanotubes, wherein the rod-like nanostructures or the nanotubes are well-dispersed, and performing vacuum filtration of the solution through a filtration membrane, wherein the vacuum filtration produces a film on the filtration membrane where the rod-like nanostructures or the nanotubes are aligned. The well-dispersed individual rod-like nanostructures or nanotubes may be separately suspended in the solution. The concentration of rod-like nanostructures or nanotubes may be below a threshold value and/or the filtration speed may be as slow as possible. Where a surfactant is utilized to aid dispersion, the surfactant concentration may be below a critical micelle concentration (CMC).
