Measurement results of five steel samples with a roughn... Crossed vortex bottle beam trap for single-atom qubits [作者：Li, G; Zhang, S; Isenhower, L; Maller, K; Saffman, M,期刊：OPTICS LETTERS, 页码：851-853 , 文章类型： Article，,卷期：2012年37-5] We demonstrate trapping and quantum state control of single cesium atoms in a 532 nm wavelength bottle beam trap. The three-dimensional trap is formed by crossing two unit charge vortex beams. Single atoms are loaded wit... Adaptive coded-aperture imaging with subpixel superresolution [作者：Slinger, C; Bennett, H; Dyer, G; Gordon, N; Huckridge, D; McNie, M; Penney, R; Proudler, I; Rice, K; Ridley, K; Russell, L; de Villiers, G; Watson, P,期刊：OPTICS LETTERS, 页码：854-856 , 文章类型： Article，,卷期：2012年37-5] We describe an adaptive coded-aperture imager operating in the midwave IR. This consists of a coded-aperture mask, a set of optics, and a 4k x 4k focal plane array (FPA). This system can produce images with a resolution ... Multiple filamentation generated by focusing femtosecond laser with axicon [作者：Sun, XD; Gao, H; Zeng, B; Xu, SQ; Liu, WW; Cheng, Y; Xu, ZZ; Mu, GG,期刊：OPTICS LETTERS, 页码：857-859 , 文章类型： Article，,卷期：2012年37-5] Multiple filamentation has been observed when focusing a femtosecond laser pulse into a methanol solution with an axicon. It is found that multiple long filaments are located on the central spot and ring structures of th... Origin of thermally induced second harmonic generation in PbO-B2O3 glasses [作者：Liu, QM; Du, JC,期刊：OPTICS LETTERS, 页码：860-862 , 文章类型： Article，,卷期：2012年37-5] Optical second harmonic generation (SHG) with second-order nonlinearity chi((2)) as high as 2.1 pm/V has been achieved in water quenched PbO-B2O3 glasses. No nonlinear depletion layer or microcrystals were observed in th... Temperature sensor based on an isopropanol-sealed photonic crystal fiber in-line interferometer with enhanced refractive index sensitivity [作者：Qiu, SJ; Chen, Y; Xu, F; Lu, YQ,期刊：OPTICS LETTERS, 页码：863-865 , 文章类型： Article，,卷期：2012年37-5] We fabricate a simple, compact, and stable temperature sensor based on a liquid-sealed photonic crystal fiber (PCF) in-line nonpolarimetric modal interferometer. Different from other reported PCF devices, it does not nee... Polarization-modulated analog photonic link with compensation of the dispersion-induced power fading [作者：Zhang, HT; Pan, SL; Huang, MH; Chen, XF,期刊：OPTICS LETTERS, 页码：866-868 , 文章类型： Article，,卷期：2012年37-5] A novel integrable modulator consisting of a polarization modulator and a polarizer is proposed for constructing a high-performance analog photonic link. By adjusting a polarization controller placed before the modulator... Characterization of dielectric spheres by spiral imaging [作者：Petrov, D; Rahuel, N; Molina-Terriza, G; Torner, L,期刊：OPTICS LETTERS, 页码：869-871 , 文章类型： Article，,卷期：2012年37-5] We study the spiral spectra scattered off transparent dielectric spheres when probed by different Laguerre-Gaussian light beams, carrying nested topological wavefront dislocations. We show that such scattering data may b... Dual-modality photothermal optical coherence tomography and magnetic-resonance imaging of carbon nanotubes [作者：Tucker-Schwartz, JM; Hong, T; Colvin, DC; Xu, YQ; Skala, MC,期刊：OPTICS LETTERS, 页码：872-874 , 文章类型： Article，,卷期：2012年37-5] We demonstrate polyethylene-glycol-coated single-walled carbon nanotubes (CNTs) as contrast agents for both photothermal optical coherence tomography (OCT) and magnetic-resonance imaging (MRI). Photothermal OCT was accom... Chip-based frequency combs with sub-100 GHz repetition rates [作者：Johnson, AR; Okawachi, Y; Levy, JS; Cardenas, J; Saha, K; Lipson, M; Gaeta, AL,期刊：OPTICS LETTERS, 页码：875-877 , 文章类型： Article，,卷期：2012年37-5] By fabricating high-Q silicon-nitride spiral resonators, we demonstrate frequency combs spanning over 200 nm with free spectral ranges (FSRs) of 80, 40, and 20 GHz using cascaded four-wave mixing. We characterize the RF ...
