Abstract: A metasurface device includes a dielectric layer, an aluminum nanodisk and an aluminum layer. The dielectric layer includes top and bottom surfaces that are opposite each other. The dielectric layer also includes at least one ring-like cavity that extends between the top and bottom surfaces of the dielectric layer. The aluminum nanodisk is formed in the at least one ring-like cavity in the dielectric layer. The aluminum layer is formed on the dielectric layer and includes at least one ring-like cavity that extends between top and bottom surfaces of the aluminum layer. Each ring-like cavity in the aluminum layer corresponds to a ring-like cavity in the dielectric layer. Two or more analytes may emit fluorescence in response to light of a predetermined wavelength being incident on the metasurface device and in which the two or more analytes are present at the dielectric layer.

Abstract: A long-wave infrared detecting element includes a magnetic field generator configured to generate a magnetic field; a substrate on the magnetic field generator; a superparamagnetic material layer disposed to be separated from the substrate and magnetized by the magnetic field generated by the magnetic field generator; a support unit on the substrate to support the superparamagnetic material layer such that the superparamagnetic material layer separated from the substrate, such that the support unit and the superparamagnetic material layer generate heat by absorbing infrared radiation from the outside; and a magneto-electric conversion unit that generates an electrical signal proportional to both a strength of the magnetic field generated by the magnetic field generator and the magnetization of the superparamagnetic material layer.

Abstract: A biosensor includes a periodic crystalline structure first layer, and an amorphous crystalline structure second layer. The first and second layers are formed from a biocompatible silicone having a Young's Modulus E between 0.4 and 2.0 MPa. The biosensor has a pressure dependent NIR resonance peak shift of less than 15 nm over a field of view of 40°, and has an optical pressure sensitivity of between 0.38 and 2.6 nm/mm Hg. The biosensor may be formed by forming a 3D crystalline structure having a periodic amorphous crystalline first layer and an amorphous crystalline second layer. Voids of the 3D crystalline structure are filled with the biocompatible silicone/polydimethylsiloxane a material. The 3D crystalline structure is removed to form an inverse structure having a first volume of an amorphous arrangement of voids and a second volume of a periodic arrangement of voids.

Abstract: Optical spectrometers may be used to determine the spectral components of electromagnetic waves. Spectrometers may be large, bulky devices and may require waves to enter at a nearly direct angle of incidence in order to record a measurement. What is disclosed is an ultra-compact spectrometer with nanophotonic components as light dispersion technology. Nanophotonic components may contain metasurfaces and Bragg filters. Each metasurface may contain light scattering nanostructures that may be randomized to create a large input angle, and the Bragg filter may result in the light dispersion independent of the input angle. The spectrometer may be capable of handling about 200 nm bandwidth. The ultra-compact spectrometer may be able to read image data in the visible (400-600 nm) and to read spectral data in the near-infrared (700-900 nm) wavelength range. The surface area of the spectrometer may be about 1 mm2, allowing it to fit on mobile devices.
