TL;DR: In this paper, an improved description of Jones vectors of the electric fields of incident and refracted rays in a tilted birefringent plate was derived, where the electric field vector was both expressed as linear combinations of ordinary (O) and extraordinary (E) components.
Abstract: An improved description of Jones vectors of the electric fields of incident and refracted rays in a tilted birefringent plate were derived. The incident and refracted electric fields were both expressed as linear combinations of ordinary (O) and extraordinary (E) components. For the O polarization inside the plate, its electric field was directly obtained according to the ellipsoid of wave normals. The 'O component' of the incident electric field was educed by using Fresnel's equations. For the E polarization inside the plate, its displacement vector was decided by the ellipsoid of wave normals, but the electric field vector was educed with the aid of material equations. Moreover, in order to get the 'E component' of the incident electric field, Fresnel's equations were modified to satisfy the boundary conditions. Numerical examples were given to compare the difference between conventional and modified Fresnel's equations. Finally, Jones vectors for the electric fields of the incident and refracted rays were obtained.

TL;DR: A unique fabrication technique is developed that utilizes the tunability and the polarization resonance splitting inside the filter to align the birefringent axes at a pigtail-cavity joint.
Abstract: We report what are to our knowledge the first high-performance polarization-maintaining single-mode fiber Fabry-Perot tunable filters. These filters simultaneously exhibited a loss of 30 dB. A unique fabrication technique is developed that utilizes the tunability and the polarization resonance splitting inside the filter to align the birefringent axes at a pigtail-cavity joint. A general criterion is established for aligning polarization-maintaining fibers with elliptical inputs.

TL;DR: It is demonstrated that it is possible to convert a polarization microscope into a Mueller microscope by only adding two motorized rotating compensators into the optical path without altering the optics or other opto-mechanical elements of the microscope.
Abstract: This work reports the conversion of a commercial polarization microscope (Zeiss Jenaval) into an automatized Mueller matrix microscope. A Mueller matrix measurement provides the value of all the optical properties of a specimen (linear dichroism, linear birefringence, circular dichroism etc.) at a specific wavelength. In contrast to traditional polarization microscopes, which use white light and crossed polarizers to generate colored interference patterns that are analyzed by the microscope user and give only semi-quantitative results, here we demonstrate that it is possible to convert a polarization microscope into a Mueller microscope by only adding two motorized rotating compensators into the optical path without altering the optics or other opto-mechanical elements of the microscope. To our knowledge this is the most compact, fast and handy Mueller microscope ever developed. The performance of this new Mueller matrix microscope is illustrated with some birefringence measurements on textile fibers
