    Abstract: A polarimeter for measuring chirality of a material comprising an optical ring cavity comprising a plurality of reflective elements configured to promote bi-directional propagation of a laser beam within the cavity, a laser-emitting device configured to introduce a first input laser beam and a second input laser beam into the ring cavity, and a Faraday rotator and a phase compensator configured to suppress a birefringent background as the first and second laser beams pass through the ring cavity, wherein the plurality of mirrors, Faraday rotator, and phase compensator are configured such that light from the first and second laser beams passes through a chiral material located within the cavity a sufficient number of times for a measurement of optical rotary dispersion (ORD) and circular dichroism (CD) of light transmitted through the chiral material to be obtained. Particular implementations include monolithic ring cavities or microresonators or use of intra-cavity gain media.

    Abstract: A device for enhancing transmission of incident electromagnetic radiation at a predetermined wavelength is presented that includes an aperture array structure in a thin film. The structure includes a repealing unit cell having more than one aperture including a first aperture and a second aperture, wherein a parameter of the first aperture differs from that of the second aperture. The unit cell repeats with a periodicity on the order of or less than said predetermined wavelength, The structure parameters are configured to preferentially support cavity modes for coupling to and enhancing transmission of a predetermined polarization state at the predetermined wavelength. By structuring the unit cell with apertures that differ by appropriate degrees in at least one of dimension, height, dielectric constant of material filling the apertures, shape, and orientation, the devices can be adapted for polarization and/or wavelength filtering- and/or light circulating, weaving, or channeling.

    Abstract: Example embodiments of methods, apparatus, and systems for measuring polarimetric parameters using spectroscopy are disclosed herein. Particular embodiments concern circular dichroism (CD) spectrometers that use a vertically aligned beam. In such embodiments, the solution being analyzed may have a top surface that forms a convex or concave meniscus, creating a surface through which the measuring beam passes that may refract the beam in undesirable ways. Accordingly, particular embodiments of the disclosed technology include one or more meniscus-compensating (meniscus-effect-reducing) components or subsystems. These components and/or subsystems can be used alone or in combination with one another to reduce the undesirable refractive effects caused by the meniscus at the solution's surface, thereby improving the resulting quality of the spectroscopy measurement and potentially improving the speed with which CD spectroscopy can be performed.
