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.

Abstract: The present disclosure relates to a reflective optical sensor module, an optical sensing accessory, and an optical sensing device. A reflective optical sensor module comprises a light source (110) and a first encapsulant (111), a photodetector (120) and a second encapsulant (121), and a substrate (140). The light source (110) is configured to convert electric power into radiant energy and to emit light to an object surface. The photodetector (120) is configured to receive the light from an object surface and to convert radiant energy into electrical current or voltage. A partition (130) is located between the light source(110) and the photodetector (120). At least one medial surface of the encapsulants (111, 121) forms an optical directional component (113, 123) which may be an inclined plane or a lens. Optical directional components (113, 123) facilitate light extraction efficiency and light receiving efficiency, respectively. In particular, light emitted from the light source (110) can be more concentrated above the partition (130), and is less shed on partition (130). The optical sensing accessory and the optical sensing device comprise the reflective optical sensor module and other electronic modules to have further applications.
