    Abstract: An angular sensitive time-of-flight position sensor device is provided and includes an array of pixels each comprising: a planar waveguide structure; a collection area with a grating pattern at a specific periodicity to couple incident light into the planar waveguide structure; at least one detector placed outside of the collection area and in a plane different from that of the planar waveguide structure; an output coupler to direct the light from planar waveguide to the at least one detector; a mask to shield the at least one detector from direct illumination; a narrow band light source that illuminates a field-of-view; a first electronics configured to detect the time-of-flight of light retroreflected, scattered, or both incident onto the position sensor and configured to provide distance ranging information; and a second electronics configured to interpret and retain time-of-flight information and configured to communicate with external electronics for system applications.

    Abstract: Methods and apparatus for long read, label-free, optical nanopore long chain molecule sequencing. In general, the present disclosure describes a novel sequencing technology based on the integration of nanochannels to deliver single long-chain molecules with widely spaced (>wavelength), ˜1-nm aperture “tortuous” nanopores that slow translocation sufficiently to provide massively parallel, single base resolution using optical techniques. A novel, directed self-assembly nanofabrication scheme using simple colloidal nanoparticles is used to form the nanopore arrays atop nanochannels that unfold the long chain molecules. At the surface of the nanoparticle array, strongly localized electromagnetic fields in engineered plasmonic/polaritonic structures allow for single base resolution using optical techniques.

    Abstract: A spectral sensor and a method for forming the spectral sensor is disclosed. The spectral sensor includes a planar waveguide on a substrate; a restriction mechanism that restricts a range of angles of incidence of light impinging onto the chirped input coupling grating; the chirped input grating formed to couple incident light into the planar waveguide, wherein the chirped input coupling grating comprises a first transverse chirp to provide a spectrally selective coupling of incident light Into the planar waveguide; a propagation region to filter out light that is not coupled into the planar waveguide; a detector array arranged on the opposite side of the propagation region from the chirped input coupling S grating to receive light coupled out of the planar waveguide and produce output signals representative of the light; and an electrical circuit to readout output signals from the detector array.

    Abstract: A method and system for high-speed 2Θ multi-point scatterometry is disclosed. The method includes directing a laser beam from a laser light source to a collimation optical system that collimates the laser beam to a collimated laser beam; adjusting a polarization of the collimated laser beam using a polarization control optics; directing the collimated laser beam that is polarized by a first optical system to illuminate a focal area on a sample surface; receiving reflected light from the focus of the laser light source at the sample surface by a second optical system; detecting the reflected light by a detector system to produce detection signals; and processing the detection signals to measure parameters of the sample surface.
