- Tunable microwave generation based on a dual-wavelength fiber laser with an inverse-Gaussian apodized fiber Bragg grating
[作者:Lin, B; Tjin, SC; Jiang, M; Shum, P,期刊:APPLIED OPTICS, 页码:4912-4916 , 文章类型: Article,,卷期:2011年50-25]
- A dual-wavelength single-longitudinal-mode erbium-doped fiber ring laser, comprising an inverse-Gaussian apodized fiber Bragg grating (IGAFBG) with two passbands and a saturable absorber, is proposed. The wavelength spac...
- Evaluation of a time-frequency domain interferometer for simultaneous group-velocity dispersion measurements in multimode photonic crystal fibers
[作者:Boswetter, P; Baselt, T; Ebert, F; Basan, F; Hartmann, P,期刊:APPLIED OPTICS, 页码:E32-E37 , 文章类型: Article,,卷期:2011年50-25]
- Fiber optical applications are primarily limited by group-velocity dispersion. In single-mode fibers, material and waveguide dispersion yield a total chromatic dispersion where no modal influences occur. However, modal d...
- Mode-field expansion in photonic crystal fibers
[作者:Xi, XM; Chen, ZL; Sun, GL; Hou, J,期刊:APPLIED OPTICS, 页码:E50-E54 , 文章类型: Article,,卷期:2011年50-25]
- We propose two novel methods to make mode-field expanders using photonic crystal fibers (PCFs). By heating and collapsing the center rings of airholes around the core using the selective airhole collapse technique, we en...
- High-speed electrical switching in optical fibers [Invited]
[作者:Margulis, W; Yu, ZW; Malmstrom, M; Rugeland, P; Knape, H; Tarasenko, O,期刊:APPLIED OPTICS, 页码:E65-E75 , 文章类型: Article,,卷期:2011年50-25]
- In this paper, we give an overview of recent results on switching of light in fibers with internal electrodes. Polarization rotation, nanosecond gating, and wavelength switching in fiber Bragg gratings and in long period...
- Evaluation of the performance of high phosphorous with germanium codoped multimode optical fiber for use as a radiation sensor at low dose rates
[作者:Ghosh, S; Das, S; Paul, MC; Dasgupta, K; Bohra, D; Chaudhary, HS; Panwar, L; Bhatnagar, PK; Vaijapurkar, SG,期刊:APPLIED OPTICS, 页码:E80-E85 , 文章类型: Article,,卷期:2011年50-25]
- We propose a GeO(2)-P(2)O(5)-codoped step index multimode (SIMM) fiber having a core diameter of around 50 mu m with numerical aperture of around 0.21-0.22. The proposed SIMM fiber shows excellent linear radiation respon...
