    Abstract: An optical sensor readout Interrogates an optical sensor and includes: a microcavity sensor that receives an optical frequency comb, produces a post-sensor optical frequency comb from the optical frequency comb based on a physical perturbation subjected to the microcavity sensor, and communicates the post-sensor optical frequency comb to a photo detector; an electro optic modulator in optical communication with the microcavity sensor and that receives input light and a radiofrequency drive signal, produces the optical frequency comb from the input light based on the radiofrequency drive signal, and communicates the optical frequency comb to the microcavity sensor; and the photo detector in optical communication with the microcavity sensor and that: receives the post-sensor optical frequency comb from the microcavity sensor; receives frequency shifted light; and produces a radiofrequency interferogram from interference between the post-sensor optical frequency comb and the frequency shifted light.

    Abstract: A temporal magnification spectrometer includes a dual-chirp comb source, a signal leg, a local oscillator leg, an optical detector, and a temporal magnification analyzer. The dual-chirp comb source produces optical carrier laser light. A signal comb having signal linearly chirped waveforms interacts with a sample to produce a transmitted signal comb. The local oscillator leg produces a local oscillator comb having local oscillator linearly chirped waveforms. The optical detector receives the transmitted signal and local oscillator combs and produces an RF domain signal. The analyzer receives and Fourier transforms the RF domain signal to produce an RF comb, which is sampled to produce sampled RF comb lines, which are normalized to produce temporally magnified sample frequency domain data. Intermediate sample temporal data are normalized to produce a steady-state sample spectral response.

    Abstract: A metallic grating is formed to include a substrate; a plurality of high aspect ratio trenches disposed in the substrate such that the high aspect ratio trenches are spaced apart from one another by a field surface of the substrate; a metallic superconformal filling formed and disposed in the high aspect ratio trenches; and a grating including a spatial arrangement of the high aspect ratio trenches that are filled with the metallic superconformal filling such that the metallic superconformal filling is void-free, and the high aspect ratio trenches are bottom-up filled with the metallic superconformal filling, wherein a height of the metallic superconformal filling is less than or equal to the height of the high aspect ratio trenches.

    Abstract: An optomechanical accelerometer includes: a fiducial mass for a microscale Fabry-Perot optical cavity; a proof mass for the microscale Fabry-Perot optical cavity, such that the proof mass oscillates in a displacement motion toward and away from the fiducial mass in response to acceleration of the optomechanical accelerometer; a basal member; microscale beams that mechanically suspend the proof mass from the basal member; and the microscale Fabry-Perot optical cavity that has a cavity resonance at a cavity resonance wavelength provided by the cavity length, receives excitation radiation at an excitation wavelength that is reflected in the cavity as dynamic cavity light when the excitation wavelength is resonant with the cavity resonance wavelength, and transmits the dynamic cavity light as cavity output light when the dynamic cavity light is produced from the excitation radiation.

    Abstract: A molecular scrivener reads data from or writes data to a macromolecule and includes: a pair of shielding electrodes; a scrivener electrode between the first and second shielding electrodes and that electrically floats at a third potential that, in an absence of a charged or dipolar moiety of the macromolecule, is intermediate between the first and second potentials and changes in a presence of the charged or dipolar moiety; a dielectric layer interposed between shielding electrodes and the scrivener electrode; and a nanopore that communicates the macromolecule through the electrodes and dielectric layers. Reading data from or writing data to a macromolecule includes: sequentially receiving, at the scrivener electrode, individual moieties of the macromolecule so that the third potential responds to individual moieties; communicating the macromolecule from the scrivener electrode to the second shielding electrode and from second shielding electrode to expel the macromolecule from the nanopore.
