Principal linear polarization states of an optical system

Principal linear polarization states of an optical system

Loci of invariant-azimuth and invariant-ellipticity polarization States of an optical system.

The loci of polarization states for which either the ellipticity alone or the azimuth alone remains invariant upon passing through an optical system are introduced. The cartesian equations of these two loci are derived in the complex plane in which the polarization states are represented. The equations are quartic and are conveniently expressed in terms of the elements of the Jones. matrix of t...

Optical Linear Polarization of Late M-and L-type Dwarfs

We report on the linear polarimetric observations in the Johnson I-band filter of 44 ultracool dwarfs with spectral types between M6 and L7.5, corresponding to effective temperatures in the range 2800–1400 K, and one M4.5-type star. Based on our measurements of polarization (P) and their associated error bars (σ P), eleven (10 L and 1 M) dwarfs appear to have significant linear polarization (P/...

Spatially engineered polarization states and optical vortices in uniaxial crystals.

We describe how the propagation of light through uniaxial crystals can be used as a versatile tool towards the spatial engineering of polarization and phase, thereby providing an all-optical technique for vectorial and scalar singular beam shaping in optics. Besides the prominent role played by the linear birefringence, the influence of circular birefringence (the optical activity) is discussed...
