We demonstrate a fast optical modulator capable of switching large amount of optical retardation (a few microns) in less than 1 ms. The result is achieved by employing a dual frequency nematic in cells with high pre-tilt alignment and by providing a special addressing scheme that features amplitude and frequency modulated voltage. We explore the effect of time delay and dielectric heating in pr...

We have devised a full-resolution stereoscopic television system incorporating both a patterned retarder and active glasses. Selective vision of the left image by the left eye and the right image by the right eye is achieved by a conventional combination of a patterned retarder and left and right polarized filters. Full resolution is provided by the active components of the glasses acting as a ...

We study the structure of linear codes over the ring Bk which is defined by Fpr [v1, v2, . . . , vk]/〈v 2 i = vi, viv j = v jvi〉 k i, j=1. In order to study the codes, we begin with studying the structure of the ring Bk via a Gray map which also induces a relation between codes over Bk and codes over Fpr . We consider Euclidean and Hermitian self-dual codes, MacWilliams relations, as well as Si...

By using the formal analogy between the evolution of the state vector in quantum mechanics and the Jones vector in polarization optics, we construct and demonstrate experimentally efficient broadband half-wave polarization retarders and tunable narrowband polarization filters. Both the broadband retarders and the filters are constructed by the same set of stacked standard multi-order optical wa...

In practical applications, the analysis and control on polarization state are important. The spun birefringent optical fiber has diverse characteristics. It can be used to manufacture linear maintaining (PM) fibers, rotators, retarders, arbitrary of fibers. To understand diversity fiber, an analytical model based Jones matrix is established. a general which could explain why so many behaviors. ...

A novel experimental technique for the realisation of optical Faraday effect using Laguerre- Gaussian (LG) light is described. The experiment employs a zero-order vortex half-wave retarder to generate radially or azimuthally-polarised LG doughnut beam. emerging from then passes through linear polariser, which gives rise two intensity lobes, with orientation gap between lobes pointing parallel (...
