Polarized Light

Application of the Manakov-PMD equation to studies of signal propagation in optical fibers with randomly varying birefringence

“…The other solution of (7) is given by . We define the Stokes parameters of the CW wave as (14) Using the solutions and , we also define (15) Defining the real vectors and recalling that at and , it can be shown that the are vectors on the Poincaré sphere [11] and that is initially pointed in the -direction, is initially pointed in the -direction, and is initially pointed in the -direction. As T evolves in accordance with (10), the will wander on the surface of the Poincaré sphere but will remain orthogonal to each other.…”

Time-Resolved Profiles in Modulated Polarization Spectroscopy

“…The Jones representation 10,13,14 uses a two-dimensional complex electric field vector. The other, the Stokes representation, ,, describes light by a real four-dimensional vector. Both representations have advantages and disadvantages.…”

Parallel Polarization State Generation

“…Consequently, performance characteristics, such as speed, stability, and spectral range, are entirely dictated by the technologies of optical intensity modulation, including absorption, reflection, emission, and scattering. This opens up important prospects for polarization state generation (PSG) with unique performance characteristics and applications in spectroscopic ellipsometry, spectropolarimetry, communications, imaging, and security.In everyday use, SOPs are commonly met in the so-called "degenerate polarizations" as linearly and circularly polarized light but are in general elliptically polarized 3,4 . To describe and control the polarization of light, the projections of the electric field onto an orthogonal bases and their relative phase relation must be known and are mathematically represented by the Jones vector and Stokes Parameters 1,5 (see Supplementary Information).In conventional serial architectures, the polarization of an input beam, E in , may be transformed into any arbitrary output polarization, E out , through a product of Jones matrices M n corresponding to variable optical elements, each of which has a degree of freedom, ρ n : E out = M N (ρ N )…M 2 (ρ 2 )M 1 (ρ 1 )E in .…”
