Optics Communications, 1976
In the following a polarizer will be described whose dielectric multilayer is not incorporated as a discontinuity in the planar waveguide as in /1/ but is deposited as a superstrate. A polarizer in the form of a dielectric multilayer and a glass plate (refractive index nG) is deposited as a superstrate on a planar waveguide (refractive index nF, film ...

Hyperfine Interactions, 2000
The principles behind the design and operation of polarization‐based optics for nuclear resonant scattering of synchrotron radiation are discussed. With perfect single crystals and collimated X‐rays emitted from undulator‐based third‐generation synchrotron radiation sources, polarization‐selective optics with a sensitivity of parts per billion can be ...

Optically Programmable Circularly Polarized Photodetector
ACS Nano, 2022The detection of circularly polarized light (CPL) has aroused wide attention from both the scientific and industrial communities. However, from the optical activity of the chiral layer in the conventional CPL photodetectors, the sign inversion property is difficult to be achieved.

Disorientated optical polarization devices
Optics Letters, 2011By using a pure operatorial (nonmatrix) approach to some of the variable composite polarization devices, we show that for some values of the variable internal parameters, these devices lose their anisotropy. Their principal axes, or more generally their eigenvectors, become undetermined, i.e., in this sense, the anisotropic devices get "disorientated."

Polarization and optical logic
Applied Optics, 1986The design of an optical logic parallel processor is described. The central component is a Fabry-Perot cavity, filled with a nonlinear layer and a linear anisotropic layer, such as a sheet of mica. The two logic states are represented by two orthogonal states of the polarization of the light beam.

Compact polarization-independent optical circulator
Applied Optics, 1981This paper introduces a compact polarization-independent optical circulator for communications using multimode optical fibers. This circulator consists of two pairs of rutile prisms used as polarization separators, a YIG Faraday rotator, a ring-shaped magnet, and a quartz halfwave plate.

Partially polarized fiber-optic gyro
Optics Letters, 1996We present a new design for an all-fiber-optic gyroscope that makes use of a single-mode coil containing a Lyot depolarizer along with a partial depolarizer placed between the polarizer and the loop coupler. This design provides an optimal trade-off between the suppression of polarization errors and the reduction of drift errors arising from external ...

Circularly polarized optical spatial solitons
Optics Letters, 2005We present, experimentally and theoretically, a polymer material system that supports optical spatial solitons of circular polarization. We demonstrate one-dimensional circularly polarized dark solitons supported by photoisomerization nonlinearity in a bulk polymer.

Single-mode fiber-optic polarizer
Optics Letters, 1980A technique is presented for the fabrication of high-quality single-mode fiber-optic polarizers. Properties of polarizers made using this technique include extinction ratios in excess of 60 dB as well as low loss for the desired polarization.

Optical polarization tractography based on polarization-sensitive optical coherence tomography
SPIE Proceedings, 2016Fibrous tissues exist in many parts of the body, where the directional fiber organization is critical in maintaining their normal functions. Disruption of the normal fibrous structure is often linked to tissue dysfunction. An imaging tool that can reveal the detailed fiber architecture will be valuable for our understanding of the structure-function ...
