摘要： Embodiments relate to a sensor structure for an acoustical pressure sensor and an opto-mechanical sensor and system that may be used for detecting acoustical pressure waves. Embodiments of a sensor structure for an acoustical pressure sensor include an optical waveguide closed-loop resonator and a plurality of sensor elements. The individual sensor elements of the plurality of sensor elements are configured to be affected by an acoustical pressure wave such that a physical property of the individual sensor element is changed. The optical waveguide closed-loop resonator is arranged at the plurality of sensor elements and associated with each of the individual sensor elements such that a resonance frequency of the optical waveguide closed-loop resonator is shifted due to the affected physical properties of all individual sensor elements. The sensor structure provides a high sensitivity from each sensor element, which is advantageous in e.g. ultrasonic imaging, such as photo-acoustic imaging where the signals typically are low.

摘要： A spectroscopic laser sensor based on hybrid III-V/IV system-on-a-chip technology. The laser sensor is configured to either (i) be used with a fiber-optic probe connected to an intravenous/intra-arterial optical catheter for direct invasive blood analyte concentration level measurement or (ii) be used to measure blood analyte concentration level non-invasively through an optical interface attached, e.g., to the skin or fingernail bed of a human. The sensor includes a III-V gain-chip, e.g., an AlGaInAsSb/GaSb based gain-chip and a photonic integrated circuit, with laser wavelength filtering, laser wavelength tuning, laser wavelength monitoring, laser signal monitoring and signal output sections realized on a chip by combining IV-based semiconductor substrates and flip-chip AlGaInAsSb/GaSb based photodetectors and embedded electronics for signal processing. Embodiments of the invention may be applied for real-time monitoring of critical blood analyte concentration levels such as lactates, urea, glucose, ammonia, albumin, etc.

摘要： The present invention relates to a method for writing data comprising a sequence of bits, the data being written in a form of nucleic acid, by in-vitro enzymatically producing memory nucleic acid from a strand of memory writing substrate nucleic acid, wherein the strand of memory writing substrate nucleic acid comprises a plurality of spacer sections and memory writing sections sandwiched between the spacer sections. Each of the spacer sections comprises one or more nucleobases, and each of the memory writing sections comprises a nucleobase other than the nucleobases of an adjacent spacer section upstream of the memory writing section in a travel direction of an enzyme along the strand of memory writing substrate nucleic acid. The method comprising: repeating of: synthesising, in liquid medium comprising the strand of memory writing substrate nucleic acid contacted with the enzyme, a spacer portion of the memory nucleic acid from a spacer section by the enzyme by contacting with a solution of spacer nucleotides compatible with the nucleobases of the spacer section; halting the synthesising of the spacer portion in a position where the enzyme is reaching the memory writing section resulting from incompatibility between spacer nucleotides and nucleobases of the portion of the memory nucleic acid from the memory writing section; receiving a sub-sequence of the sequence of bits, said sub-sequence comprising at least one bit; selecting a memory nucleotide compatible with the nucleobase of the memory writing section, and comprising a first label or first modification, on a condition that said sub-sequence comprises a predetermined first sequence of bit-values, and selecting a memory nucleotide compatible with the nucleobase of the memory writing section, and comprising a second label or second modification, on a condition that said sub-sequence comprises a predetermined second sequence of bit-values; and subsequent to the halting, synthesising, in the liquid medium comprising the strand of memory writing substrate nucleic acid contacted with the enzyme, a memory portion of the memory nucleic acid from the memory writing section by the enzyme by contacting the enzyme with a solution of the selected memory nucleotide.

摘要： A dispersive optical phased array for two-dimensional scanning is disclosed herein. The array comprises antenna blocks positioned adjacent one another. The antenna blocks comprise a plurality of antennas positioned adjacent one another and a plurality of delay lines to couple a coherent source signal to each of the antennas within the block, each delay line having an optical path length. Each of the antenna blocks acts as a dispersive phased array. The antenna blocks are arranged such that the blocks form a larger phased array where the antennas between the blocks are in phase for a discrete set of wavelengths. All antennas over the dispersive phased array can experience the same phase difference such that the beams of the individual antenna blocks align with one of the diffraction orders of the array of blocks.
