    Abstract: An image sensor includes a substrate, thin lenses disposed on a first surface of the substrate and configured to concentrate lights incident on the first surface, and light-sensing cells disposed on a second surface of the substrate, the second surface facing the first surface, and the light-sensing cells being configured to sense lights passing through the thin lenses, and generate electrical signals based on the sensed lights. A first thin lens and second thin lens of the thin lenses are configured to concentrate a first light and a second light, respectively, of the incident lights onto the light-sensing cells, the first light having a different wavelength than the second light.

    Abstract: Systems and methods for providing optical quantum communication networks based on rare-earth ion quantum bits (qubits) entrapped in solids are presented. According to one aspect a qubit is provided by an 171Yb3+ ion doped into a YVO crystal structure. A nanophotonic cavity fabricated in the doped crystal structure provides a zero-field energy level structure of the ion with optical transitions between ground and excited states at a wavelength longer than 980 nm. A subspace of the qubit is provided by two lower energy levels at the ground states separated by a microwave frequency of about 675 MHz. Addressing of the optical transitions is via first and second lasers and addressing of microwave transitions at the ground and excited states are via respective microwave sources. A single-shot readout sequence of the qubit based on two consecutive readout sequences on the optical transitions separated by a microwave pumping of the ground states is presented. Assignment of a readout state is conditionally based on combined states detected in the two consecutive readout sequences.

    Abstract: A spectrometer includes a transparent substrate including a first surface and a second surface that face each other and are substantially parallel to each other; a slit provided on the first surface and through which light is incident onto the transparent substrate; a spectrum optical system including metasurface including a plurality of nanostructures that are two-dimensionally arranged and satisfy a sub-wavelength scattering condition, wherein the metasurface includes a focusing metasurface which includes first nanostructures of the plurality of nanostructures, and is configured to reflect, disperse, and focus the light incident thereon through the slit, at different angles based on respective wavelengths; and a sensor configured to receive the light from the focusing metasurface. When L is a total length of an optical path from the slit to the sensor and D is a thickness of the transparent substrate, L and D satisfy the following inequality: L/D>3.
