Abstract: According to an example, apparatuses for performing multiple concurrent spectral analyses on a sample under test include an optical system to concurrently direct a plurality of light beams onto analytes at multiple locations on the sample under test, in which the plurality of light beams cause light in either or both of a Raman spectra and a non-Raman spectra to be emitted from the analytes at the multiple locations of the sample under test. The apparatuses also include a detector to concurrently acquire a plurality of spectral measurements of the light emitted from the analytes at the multiple locations of the sample under test. Example methods of performing spectral analysis include use of the apparatuses.

Abstract: Polarization selective surface enhanced Raman spectroscopy (SERS) includes a plurality of nanofingers arranged as a SERS multimer to exhibit a polarization-dependent plasmonic mode and one or both of a stimulus source and a Raman detector. The stimulus source is to illuminate the SERS multimer with a stimulus signal and the Raman detector is to detect a Raman scattering signal emitted by an analyte in a vicinity of the SERS multimer. One or both of the Raman scattering signal has a polarization state dictated by or associated with the polarization-dependent plasmonic mode and the stimulus signal has a polarization state corresponding to the polarization-dependent plasmonic mode.

Abstract: Liquid crystal coupled light modulation includes a light guide to guide light by total internal reflection (TIR), a diffraction grating and a liquid crystal sandwiched between the diffraction grating and the light guide. The liquid crystal has a state with a first refractive index to defeat TIR and another state with a second refractive index to facilitate TIR at a surface of the light guide. The liquid crystal in the first refractive index state is to couple out a portion of the guided light to the diffraction grating and the diffraction grating is to provide diffractive redirection of the coupled portion out of the light modulator.
