[作者:Borovkova, OV; Kartashov, YV; Lobanov, VE; Vysloukh, VA; Torner, L,期刊:OPTICS LETTERS, 页码:2176-2178 , 文章类型: Article,,卷期:2011年36-12]
- We introduce a general approach for generation of sets of three-dimensional quasi-nonspreading wave packets propagating in linear media, also referred to as linear light bullets. The spectrum of rigorously nonspreading w...
- Group velocity manipulation in active fibers using mutually modulated cross-gain modulation: from ultraslow to superluminal propagation
[作者:Qian, K; Zhan, L; Zhang, L; Zhu, ZQ; Peng, JS; Gu, ZC; Hu, X; Luo, SY; Xia, YX,期刊:OPTICS LETTERS, 页码:2185-2187 , 文章类型: Article,,卷期:2011年36-12]
- We propose and experimentally demonstrate the propagation of slow/fast light in an erbium-doped fiber (EDF) using mutually modulated cross-gain modulation. The group velocity of the light signal can be manipulated by the...
- Fiber refractometer based on a fiber Bragg grating and single-mode-multimode-single-mode fiber structure
[作者:Wu, Q; Semenova, Y; Yan, BB; Ma, YQ; Wang, PF; Yu, CX; Farrell, G,期刊:OPTICS LETTERS, 页码:2197-2199 , 文章类型: Article,,卷期:2011年36-12]
- A refractive index (RI) sensor based on a novel fiber structure that consists of a single-mode-multimode-single-mode(SMS) fiber structure followed by a fiber Bragg grating was demonstrated. The multimode fiber in the SMS...
- Multifocus with small size, uniform intensity, and nearly circular symmetry
[作者:Guo, HM; Dong, XM; Weng, XY; Sui, GR; Yang, N; Zhuang, SL,期刊:OPTICS LETTERS, 页码:2200-2202 , 文章类型: Article,,卷期:2011年36-12]
- We investigate in detail the focusing properties of the composite vector beam (CVB) composed of two orthogonally linearly polarized beams with inhomogeneous polarization modulation. By optimizing the modulation factor, a...
- High quality factor nitride-based optical cavities: microdisks with embedded GaN/Al(Ga)N quantum dots
[作者:Mexis, M; Sergent, S; Guillet, T; Brimont, C; Bretagnon, T; Gil, B; Semond, F; Leroux, M; Neel, D; David, S; Checoury, X; Boucaud, P,期刊:OPTICS LETTERS, 页码:2203-2205 , 文章类型: Article,,卷期:2011年36-12]
- We compare the quality factor values of the whispering gallery modes of microdisks (mu-disks) incorporating GaN quantum dots (QDs) grown on AlN and AlGaN barriers by performing room temperature photoluminescence (PL) spe...
- X-ray spatial harmonic imaging of phase objects
[作者:Liu, YN; Ahr, B; Linkin, A; Diebold, GJ; Rose-Petruck, C,期刊:OPTICS LETTERS, 页码:2209-2211 , 文章类型: Article,,卷期:2011年36-12]
- Refractive index gradients in materials or at material interfaces lead to x-ray diffraction. Interference of this radiation with adjacent x-ray waves causes phase contrast that can be used for imaging purposes if an x-ra...
- Distinguishing fingerprints of hyperchaotic and stochastic dynamics in optical chaos from a delayed opto-electronic oscillator
[作者:Soriano, MC; Zunino, L; Larger, L; Fischer, I; Mirasso, CR,期刊:OPTICS LETTERS, 页码:2212-2214 , 文章类型: Article,,卷期:2011年36-12]
- In the dynamics of optical systems, one commonly needs to cope with the problem of coexisting deterministic and stochastic components. The separation of these components is an important, although difficult, task. Often t...
- Cellular resolution optical coherence microscopy with high acquisition speed for in-vivo human skin volumetric imaging
[作者:Lee, KS; Thompson, KP; Meemon, P; Rolland, JP,期刊:OPTICS LETTERS, 页码:2221-2223 , 文章类型: Article,,卷期:2011年36-12]
- In this Letter, we report for the first time (to our knowledge) in-vivo volumetric optical coherence microscopy images of skin epidermal cells. We achieved micrometer-class resolution, 2 mu m laterally and axially, with ...
