Mean-square coherent light
Philippe R??er
Mean-square coherent light is defined as light that is able to interfere with fringes of unit visibility when its electromagnetic field is multiplied by appropriate nonsingular deterministic Jones matrices. It includes light that satisfies the factorization condition at order one and partially ... [Opt. Lett. 33, 1551-1553 (2008)]

Polarizing beam splitter of deep-etched triangular-groove fused-silica gratings
Jiangjun Zheng, Changhe Zhou, Jijun Feng, Bo Wang
We investigated the use of a deep-etched fused-silica grating with triangular-shaped grooves as a highly efficient polarizing beam splitter (PBS). A triangular-groove PBS grating is designed at a wavelength of 1550 nm to be used in optical communication. When it is illuminated in Littrow mounting, ... [Opt. Lett. 33, 1554-1556 (2008)]

Fractional decay of quantum dots in real photonic crystals
Philip Kristensen, A. Femius Koenderink, Peter Lodahl, Bjarne Tromborg, Jesper M?br/>We show that fractional decay may be observable in experiments using quantum dots and photonic crystals with parameters that are currently achievable. We focus on the case of inverse opal photonic crystals and locate the position in the crystal where the effect is most pronounced. Furthermore, we ... [Opt. Lett. 33, 1557-1559 (2008)]

Continuously chirped fiber Bragg gratings by femtosecond laser structuring
Jens Thomas, Christian Voigtl?er, Damian Schimpf, Fabian Stutzki, Elodie Wikszak, Jens Limpert, Stefan Nolte, Andreas T?rmann
We report on what we believe to be the first successful inscription of continuously chirped fiber Bragg gratings (CCFBG) into a nonphotosensitive single-mode fiber (SMF) with near-IR femtosecond laser pulses. The continuous chirp was achieved by inscribing into a bent fiber using a phase mask ... [Opt. Lett. 33, 1560-1562 (2008)]
