Acoustic modal analysis and control in w-shaped triple-layer optical fibers with highly-germanium-doped core and F-doped inner cladding Weiwen Zou, Zuyuan He, Kazuo Hotate The numerical study of acoustic modal properties in w-shaped optical fibers with high-delta germanium-doped core and F-doped inner cladding (F-HDF) is demonstrated. The cutoff conditions of acoustic modes in the F-HDF show opposite behaviors in contrast with those of optical ones because F-doped ... [Opt. Express 16, 10006-10017 (2008)] Design of the Advanced LIGO recycling cavities Muzammil A. Arain, Guido Mueller The current LIGO detectors will undergo an upgrade which is expected to improve their sensitivity and bandwidth significantly. These advanced gravitational-wave detectors will employ stable recycling cavities to better confine their spatial eigenmodes instead of the currently installed marginally ... [Opt. Express 16, 10018-10032 (2008)] Broadband 2.12 GHz Ti:sapphire laser compressed to 5.9 femtoseconds using MIIPS Giovana T. Nogueira, Bingwei Xu, Yves Coello, Marcos Dantus, Flavio C. Cruz We report a self-starting prismless femtosecond Ti:sapphire ring laser whose repetition rate has been gradually increased from 1 to 2.12 GHz. A broadband spectrum extending from 650 to 1040 nm, in which 17% of the intracavity power is generated in a single-pass through the crystal, is preserved ... [Opt. Express 16, 10033-10038 (2008)] Control and Stabilization of bit-wise phase correlation in 160 (4 x 40) Gbit/s OTDM signal and its impact on transmission Masatoshi Kagawa, Hitoshi Murai, Hiromi Tsuji, Kensuke Sasaki, Kozo Fujii Detail of control technique of bit-wise phase correlation in 160 (4 x 40) Gbit/s optical time division multiplexing (OTDM) signal using a phase-correlation monitor based on 1-bit delay asymmetric interferometers (AIFs) is described. The 1-bit delay AIF transforms a bit-by-bit optical phase ... [Opt. Express 16, 10039-10052 (2008)] Polarization rotation locking of vector solitons in a fiber ring laser L. M. Zhao, D. Y. Tang, H. Zhang, X. Wu Polarization rotation of vector solitons in a fiber ring laser was experimentally studied. It was observed that the period of vector soliton polarization rotation could be locked to the cavity roundtrip time or multiple of it. We further show that multiple vector solitons can be formed in a ... [Opt. Express 16, 10053-10058 (2008)] Optical particle manipulation using an LC device with eight-divided circularly hole-patterned electrodes Marenori Kawamura, Mao Ye, Susumu Sato We propose an optical manipulation system by using a liquid crystal (LC) device with unique functions such as an anamorphic lens property, variable-focusing and deflection properties. The positions and rotation of optical trapped microscopic slender particles suspended in water can be controlled. ... [Opt. Express 16, 10059-10065 (2008)] A spatio-temporally compensated acousto-optic scanner for two-photon microscopy providing large field of view Y. Kremer, J.-F. L?r, R. Lapole, N. Honnorat, Y. Candela, S. Dieudonn?L. Bourdieu Acousto-optic deflectors (AOD) are promising ultrafast scanners for non-linear microscopy. Their use has been limited until now by their small scanning range and by the spatial and temporal dispersions of the laser beam going through the deflectors. We show that the use of AOD of large aperture ... [Opt. Express 16, 10066-10076 (2008)] Single molecule correlation spectroscopy in continuous flow mixers with zero-mode waveguides David Liao, Peter Galajda, Robert Riehn, Rob Ilic, Jason L. Puchalla, Howard G. Yu, Harold G. Craighead, Robert H. Austin Zero-ModeWaveguides were first introduced for Fluorescence Correlation Spectroscopy at micromolar dye concentrations. We show that combining zero-mode waveguides with fluorescence correlation spectroscopy in a continuous flow mixer avoids the compression of the FCS signal due to fluid transport at ... [Opt. Express 16, 10077-10090 (2008)] Evidence of ultra low microwave additive phase noise for an optical RF link based on a class-A semiconductor laser Ghaya Baili, Mehdi Alouini, Thierry Malherbe, Daniel Dolfi, Jean-Pierre Huignard, Thomas Merlet, Jean Chazelas, Isabelle Sagnes, Fabien Bretenaker The additive RF phase noise of a microwave photonics link is measured using, as the optical source, a semiconductor laser operating in the class-A regime. The relative intensity noise of this laser being below the shot noise relative level, the phase noise floor of the link is shown to be shot ... [Opt. Express 16, 10091-10097 (2008)] Thermal behaviour of ytterbium-doped fluorite crystals under high power pumping J. Boudeile, J. Didierjean, P. Camy, J. L. Doualan, A. Benayad, V. M?rd, R. Moncorg?F. Druon, F. Balembois, P. Georges We report an in situ thermal study of Yb-doped fluorite crystals Yb:CaF_2 and Yb:SrF_2 under high power pumping, with or without laser operation. The experiment combines simultaneously thermography and measurement of the thermal aberrations. This setup allows us to measure temperature gradients, ... [Opt. Express 16, 10098-10109 (2008)]
