Linear optics of polarization sheets
Applied Physics B Photophysics and Laser Chemistry, 1987We develop a theory in which thin films or monolayers of strongly polarizable molecules are described as linear polarization sheets. We show that this concept in combination with the transfer matrix method allows a transparent derivation of the transmission and reflection properties of a composite interface.

Fiber-optic polarizing directional coupler
Optics Letters, 1984A novel fiber-optic device acting simultaneously as a polarizer and a directional coupler is fabricated by coating a metal layer onto the fused biconical-taper structure of single-mode fibers. This polarizing directional coupler exhibits an extinction ratio of 15 dB together with a 1:1 power-splitting ratio and an excess loss of 2.8 dB.

Polarization-mixing optical parametric oscillator
Optics Letters, 2005We report the experimental realization of a new type of optical parametric oscillator in which oscillation is achieved by polarization rotation in a linear retarder, followed by nonlinear polarization mixing. The mixing is performed by a type II degenerate parametric downconversion in a periodically poled KTP crystal pumped by a 1064 nm pulsed Nd:YAG ...

Polarization recovery in optical polarization shift-keying systems
IEEE Transactions on Communications, 1997For the first time, a solution to the problem of recovering and tracking the signal constellation at the receiver side for binary and octonary digital optical transmission systems employing the modulation of polarization (POLSK) is proposed and analyzed.

Polarization-Independent Electrooptic Depolarizer
Integrated Photonics Research, 1995Optical depolarizers are frequently used in optical measurement equipment as well as in fiberoptic sensors to remove undesired polarization sensitivity [1]. Recently, depolarizers have also been employed in long-haul all-optical communication systems to avoid polarization hole burning (anisotropic gain saturation) in the erbium-doped fiber amplifiers ...

Optically switchable all-fiber optic polarizer
2012 Photonics Global Conference (PGC), 2012We demonstrate an optically switchable all-fiber optical polarizer based on a side-polished fiber (SPF) overlaid with a photoresponsive liquid crystal (PLC) containing a nematic LC and a photosensitive azobenzene molecule. The trans-cis photoisomerization of azobenzene modulates the overlaid LC's birefringence, changes the refractive index (RI) of the ...

Polarization‐maintaining near‐field optical probes
Journal of Microscopy, 2008SummaryWe demonstrate that tapered optical fibre probes can be easily modified in the taper cone to realize an electric dipole producing a well‐defined near‐field polarized light. This novel structure is made of a Short‐cut Double C–shaped probe design combined to the usual full metal coating near the tapered end of the fibre.

Polarization-insensitive optical amplifiers in AlInGaAs
IEEE Photonics Technology Letters, 2001We report the theoretical modeling and the fabrication of polarization-insensitive optical amplifiers at 1300 nm in AlInGaAs-InP material system. Gain calculations, using the k.p method, show that the introduction of 0.33% tensile strain into a three-quantum-well structure can achieve gain-matching over a wide energy spectrum.

1989
Publisher Summary This chapter discusses optical polarization. Polarization effects are a result of the wave interaction of light with the physical world and have long been demonstrated with a double refractive index crystal known as calcite. Light waves in two orthogonal planes are laterally separated after passing through calcite, resulting in two ...
