Second and third order frequency correlations of speckle intensity patterns are used to characterize scattering media for multiple polarization states.
We present photon-spin quantum-state-transfer (QST) approach. GaAs/AlGaAs-QW with g~0 showed nonlinear B-field dependence of spin precession, suggesting photon-to-nuclei polarization transfer. 2DEG with quantum-point-contact on InGaAs/InP showed telecomwavelength-sensitive quantum transport. Efficient/high-fidelity QST conditions were also found.
Stress-induced birefringence in a single-transverse-mode YAG laser is well compensated simply by having the end mirror one Rayleigh range away from the gain.
Complete cancellation of polarization dependency using a lambda/2-shifted Sagnac loop interferometer is quantitatively characterized for a number of commercial-graded transmission-type optical devices, such as in-line polarizer and variable optical attenuator.
We propose a new sensing method based on two quantum entangled beams. The effects caused by inserting polarizer or DNA solution into one beam can be also detected in the other undisturbed entangled beam.
We review major developments that have led to a high performance, polarization independent, microphotonic circuit. The design and fabrication of complex high-order microring-resonators, along with techniques to freely manipulate polarization states on-chip are presented.
We report a polarization-independent 80 Gb/s optical demultiplexer based on cross-phase modulation in 2 meters of bismuth-oxide fiber. We show error- and penalty-free performance even when the polarization state is randomly scrambled.
We demonstrate an all-optical polarization controller using the injection-locking induced transverse-mode switching of 1.5 mum elliptical-apertured VCSEL. The polarization of an output fundamental-mode was stabilized even for randomly polarized input light injected into a high-order transverse mode.
Long-range periodic nanoplane gratings written inside fused silica using a focused femtosecond laser beam can be erased and replaced with new gratings whose orientation is determined by the polarization of the femtosecond laser overwrite beam.
Trapping and switching of liquid crystal micron-size droplets using a lensed fiber with 1.55 mum cw light is demonstrated. Intensity modulation due to droplet rotation is achieved by controlling the power and polarization of pump light.
We determine the relative phase between bulk and surface contributions to second-harmonic generation (SHG) from Si(001) by exploiting the difference between right- and left-handed q-polarization, and by frequency-domain interferometric SHG.
A dramatic enhancement of harmonics and the extension of cutoff were observed in a linearly polarized two-color laser field below 10 nm. The intense soft X-ray supercontinuum provides an alternative for the attosecond generation.
The first experimental measurement of electron spin relaxation in GaInNAs quantum wells is reported. An all-optical polarization switch based on the excitation of spin-polarized electrons is demonstrated.
We present a microscopic description for the polarization induced in a plasma by few-cycle optical pulses in isotropic gaseous media. The resulting asymmetric polarization allows for optical rectification and THz emission.
We propose a convenient method for controlling the three-dimensional polarization vector at the focus of a high-numerical-aperture lens using a linearly polarized input field. This form of polarization microscopy requires no polarization optics.
We demonstrate a simple, robust, high-flux source of polarization-entangled photons based on a polarization Sagnac interferometer, measuring 5000 polarization-entangled pairs/s/mW of pump power in a 1-nm bandwidth with 96.8% quantum-interference visibility.
Polarization gated high harmonic generation was phase matched to produce 104 XUV photons per shot. This allowed us to observe the dependence of the XUV supercontinuum on the carrier envelope phase of the laser pulses.
23 W, single-mode linearly-polarized 0.4 nm linewidth CW generation is achieved in a polarization-maintaining fiber Raman cavity pumped by a linearly-polarized Ytterbium fiber laser and applied to 3 W 589 nm second harmonic generation in MgO-PPLN.
Highly sensitive control of anisotropic optical polarization in CdMnTe quantum wires has been studied theoretically using multi-band effective mass method. A magnetic field dramatically changes the transition probability via the sp-d exchange interaction.
We report the self-compression of linearly and circularly polarized light pulses down to the few-cycle regime by self-guided beam propagation of intense 38-fs pulses in different gases with uniform density and with a pressure gradient.
