Tight Focusing of Light Beams: Effect of Polarization, Phase, and Coherence
Tight Focusing Light Beams Effect of Polarization Phase Coherence
2013/7/3
The focusing theory of electromagnetic waves has been well developed. A scalar wave theory satisfactorily describes the focusing process for a small semi-aperture angle. However, the vectorial charact...
Abstract—This work presents a novel wavelength conversion scheme, differential cross-polarization modulation (DXPoM), using an extra birefringence delay to enhance the performance of the conventional ...
Polarization-dependent transformation of a paraxial beam upon reflection and refraction: a real-space approach
Polarization-dependent transformation paraxial beam real-space approach reflection refraction
2011/8/3
Abstract: We analyze the paraxial beam transformation upon reflection and refraction at a plane boundary. In contrast to the usual approach dealing with the beam angular spectrum, we apply the continu...

Vector beam Axially-symmetric polarization Liquid crystal
2009/6/8
Based on the optical rotatory effect of liquid crystal, we have fabricated a compact and efficient optical device for control of space-variant polarization. Using this device we generated vector beams...
Propagation of the degree of cross-polarization of a stochastic electromagnetic beam through the turbulent atmosphere
Propagation degree cross-polarization stochastic electromagnetic beam through turbulent atmosphere
2013/7/3
The behavior of the recently introduced spectral degree of cross-polarization of a stochastic electromag-netic beam-like field on propagation through the turbulent atmosphere is analyzed. Unlike the s...

2013/7/3
We investigate the polarization change of partially coherent electromagnetic vortex beams propagating in tur-bulent atmosphere. It is shown that the polarization of the beams will experience changes, ...

2010/4/13
The anisotropic momentum distribution of photoexcited hot electrons on recombination with holes at the acceptor level produces linearly polarized luminescence. It is found that the degree of linear po...
