The proposed model learns configurational rules... Plasmon-enhanced light emission based on lattice resonances of silver nanocylinder arrays [作者：Henson, J; DiMaria, J; Dimakis, E; Moustakas, TD; Paiella, R,期刊：OPTICS LETTERS, 页码：79-81 , 文章类型： Article，,卷期：2012年37-1] Diffractive arrays of silver nanocylinders are used to increase the radiative efficiency of InGaN/ GaN quantum wells emitting at near-green wavelengths. Large enhancements in luminescence intensity (up to a factor of nea... Wavelength conversion of nanosecond pulses to the mid-IR in photonic crystal fibers [作者：Herzog, A; Shamir, A; Ishaaya, AA,期刊：OPTICS LETTERS, 页码：82-84 , 文章类型： Article，,卷期：2012年37-1] We investigate degenerate four wave mixing with nanosecond pulses in fused silica photonic crystal fibers. Phase-matching curves are calculated taking into account the material and waveguide dispersion. Experiments with ... Two-photon fluorescence isotropic-single-objective microscopy [作者：Le Moal, E; Mudry, E; Chaumet, PC; Ferrand, P; Sentenac, A,期刊：OPTICS LETTERS, 页码：85-87 , 文章类型： Article，,卷期：2012年37-1] Two-photon excitation provides efficient optical sectioning in three-dimensional fluorescence microscopy, independently of a confocal detection. In two-photon laser-scanning microscopy, the image resolution is governed b... Improving the optical performance of InGaN light-emitting diodes by altering light reflection and refraction with triangular air prism arrays [作者：Kang, JH; Kim, HG; Chandramohan, S; Kim, HK; Kim, HY; Ryu, JH; Park, YJ; Beak, YS; Lee, JS; Park, JS; Lysak, VV; Hong, CH,期刊：OPTICS LETTERS, 页码：88-90 , 文章类型： Article，,卷期：2012年37-1] The effect of triangular air prism (TAP) arrays with different distance-to-width (d/w) ratios on the enhancement of light extraction efficiency (LEE) of InGaN light-emitting diodes (LEDs) is investigated. The TAP arrays ... Metrology of laser-guided particles in air-filled hollow-core photonic crystal fiber [作者：Schmidt, OA; Garbos, MK; Euser, TG; Russell, PS,期刊：OPTICS LETTERS, 页码：91-93 , 文章类型： Article，,卷期：2012年37-1] Micrometer-sized particles are trapped in front of an air-filled hollow-core photonic crystal fiber using a novel dual-beam trap. A backward guided mode produces a divergent beam that diffracts out of the core, and simul... Optical microresonator based on hollow sphere with porous wall for chemical sensing [作者：Wang, HZ; Yuan, L; Kim, CW; Han, Q; Wei, T; Lan, XW; Xiao, H,期刊：OPTICS LETTERS, 页码：94-96 , 文章类型： Article，,卷期：2012年37-1] A porous-wall hollow glass microsphere (PW-HGM) was investigated as an optical resonator for chemical vapor sensing. A single mode optical fiber taper was used to interrogate the microresonator. Adsorption of chemical mo... Generation of soft x-ray and water window harmonics using a few-cycle, phase-locked, optical parametric chirped-pulse amplifier [作者：Ishii, N; Adachi, S; Nomura, Y; Kosuge, A; Kobayashi, Y; Kanai, T; Itatani, J; Watanabe, S,期刊：OPTICS LETTERS, 页码：97-99 , 文章类型： Article，,卷期：2012年37-1] Multimillijoule, few-cycle, carrier-envelope-phase (CEP)-locked, near-IR pulses at 750 nm from an optical parametric chirped-pulse amplifier are applied to the generation of CEP-dependent, soft x-ray high harmonics aroun...
