Abstract: A wearable module for use in an optical measurement system includes a housing and a plurality of light-receiving members. The housing includes a target-side surface configured to face a surface of a body of a user when the wearable module is worn by the user. The plurality of light-receiving members protrude from the target-side surface of the housing and are configured to receive photons scattered by a target within the body of the user and guide the received photons toward a photodetector. An extent to which each of the plurality of light-receiving members protrudes from the target-side surface is adjustable such that, when the wearable module is worn by the user, each of the plurality of light-receiving members is in physical contact with the surface of the body.

Abstract: A measurement method of receiving an emission light output from an optical semiconductor element on an incident end surface of an optical probe, shifts a relative position between the optical semiconductor element and the optical probe on a plane surface intersecting with an optical axis of the emission light, measures an incident intensity of the emission light at several positions, and obtains an incident intensity pattern showing a relationship between a change in the relative position and the respective incident intensities.

Abstract: Example embodiments include an optical interrogation system with a sensing fiber having a single core, the single core having multiple light propagating modes. Interferometric apparatus probes the single core multimode sensing fiber over a range of predetermined wavelengths and detects measurement interferometric data associated with the multiple light propagating modes of the single core for each predetermined wavelength in the range. Data processing circuitry processes the measurement interferometric data associated with the multiple light propagating modes of the single core to determine one or more shape-sensing parameters of the sensing fiber from which the shape of the fiber in three dimensions can be determined.

Abstract: An integrated quantum random noise source includes a substrate, an optical oscillator that may be integral to the substrate coupled by an optical waveguide to an optical directional coupler. The optical directional coupler has two outputs that are coupled by optical waveguides to a pair of photodetectors that are part of a balanced photodetector. The balanced photodetector in response outputs an analogue signal proportional to the difference in photocurrents of the two photodetectors. The analogue output signal from the balanced photodetector is a random Gaussian-distributed signal representative of quadrature measurements on the quantum vacuum state of light. The random noise source can be coupled other apparatus to provide a source of random bits.

The devices may be integrated in a front surface of the chip and one or more optical couplers may receive the optical signals in the front surface of the chip. The optical signals may be coupled into the back surface of the chip via one or more optical fibers and/or optical source assemblies. The optical signals may be coupled to the grating couplers via a light path etched in the chip, which may be refilled with silicon dioxide. The chip may be flip-chip bonded to a packaging substrate. Optical signals may be reflected back to the grating couplers via metal reflectors, which may be integrated in dielectric layers on the chip.
