    Abstract: Disclosed is an optical sensor, including an external cavity laser configured to output sensing light and reference light; and a photodetector configured to detect a beating signal by an interference of the sensing light and the reference light output from the external cavity laser, in which the external cavity laser includes a reflecting filter including a sensing grating, to which a sensing object is attachable, and a reference grating, which is disposed on the same plane as that of the sensing grating, and outputs sensing light reflected from the sensing grating and reference light reflected from the reference grating. Accordingly, the optical sensor does not require a high-resolution spectroscope and has improved resolution and sensitivity.

    Abstract: A multi-band spectrum division device is provided, comprising: a first parabolic reflection mirror, planar multi-mirrors, an optical grating and a second parabolic mirror. The first parabolic mirror is configured to reduce the divergent angle of incident optical beam, and to generate a collimated optical beam. The planar multi-mirrors are configured to adjust the incident angles of collimated beam on the grating surface. The grating is configured to disperse the incident signals with multi-wavelengths. The second parabolic mirror is configured to focus the multi-wavelength signals on its focal plane. Besides, each of the planar multi-mirrors has different location and angle in this device.

    Abstract: The present disclosure pertains to metal or dielectric nanostructures of the subwavelength scale within the grating lines of optical diffraction gratings. The nanostructures have surface plasmon resonances or non-plasmon optical resonances. A linear photodetector array is used to capture the resonance spectra from one of the diffraction orders. The combined nanostructure super-grating and photodetector array eliminates the use of external optical spectrometers for measuring surface plasmon or optical resonance frequency shift caused by the presence of chemical and biological agents. The nanostructure super-gratings can be used for building integrated surface enhanced Raman scattering (SERS) spectrometers. The nanostructures within the diffraction grating lines enhance Raman scattering signal light while the diffraction grating pattern of the nanostructures diffracts Raman scattering light to different directions of propagation according to their wavelengths. Therefore, the nanostructure super-gratings allows for the use of a photodetector array to capture the surface enhanced Raman scattering spectra.
