Dispersion-flattened Bragg photonic crystal fiber for large capacity optical communication system
Frontiers of Optoelectronics - Tập 2 - Trang 289-292 - 2009
Wei Chen, Shiyu Li, Peixiang Lu
A novelty dispersion ultra-flattened Bragg photonic crystal fiber (PCF) has been fabricated in this paper. The fiber is composed of compound cores and periodical claddings with 11 coaxial rings. It has flattened dispersion of 8.5±1.3 ps·(nm·km)−1 in the communication wavelength range of 1460–1625 nm. Its dispersion slope alters from −0.0428 to 0.0392 ps·nm−2·km−1. The low attenuation of 0.52 dB/km...... hiện toàn bộ

Growth of phosphorus-doped p-type ZnO thin films by MOCVD
Frontiers of Optoelectronics - Tập 1 - Trang 147-150 - 2008
Zhizhen Ye, Jingrui Wang, Yazhen Wu, Xincui Zhou, Fugang Chen, Weizhong Xu, Yan Miao, Jingyun Huang, Jianguo Lü, Liping Zhu, Binghui Zhao
Phosphorus-doped p-type ZnO thin films are prepared on glass substrates by metalorganic chemical vapor deposition (MOCVD). DEZn, O2, and P2O5 powders are used as reactant and dopant sources. The p-type ZnO films are grown at a temperature between 673 K and 723 K. The best p-type sample has a low resistivity of 4.64 Ω·cm, a hole concentration of 1.61 × 1018 cm−3, and a Hall mobility of 0.838 cm2·(V...... hiện toàn bộ
Flower-like CuO hierarchical nanostructures: synthesis, characterization, and property
Frontiers of Optoelectronics - Tập 5 - Trang 429-434 - 2012
Jiarui Huang, Feng Tang, Cuiping Gu, Chengcheng Shi, Muheng Zhai
Nanoflake-based flower-like CuO nanostructures have been synthesized through thermal decomposition of [Cu(NH3)4]2+ solution without any surfactants and catalysts at low temperature. The products are characterized by X-ray diffraction (XRD) and field-emission scanning electron microscopy (FESEM). The possible formation process based on the aggregation-recrystallization mechanism is proposed. Finall...... hiện toàn bộ
Overcoming ill-posedness of diffuse optical tomography in steady-state domain
Frontiers of Optoelectronics - Tập 1 - Trang 44-49 - 2008
Guotao Quan, Kun Bi, Shaoqun Zeng, Qingming Luo
In recent decades, diffuse optical tomography (DOT) has drawn more and more interest in molecular imaging because of its advantage of large penetration depth in optical image technology. However, ill-posedness problems have dramatically limited this application technique. In this paper, a new method to remove the ill-posedness of DOT is introduced. With a rotating steady-state domain experiment sy...... hiện toàn bộ
Research on VO x uncooled infrared bolometer based on porous silicon
Frontiers of Optoelectronics - Tập 5 - Trang 292-297 - 2012
Bin Wang, Jianjun Lai, Erjing Zhao, Haoming Hu, Sihai Chen
In this paper, vanadium oxide thin film of TCR of −3.5%/K has been deposited by pulsed DC magnetron sputtering method. The property of this VO x has been investigated by X-ray diffractometer (XRD) and atomic force microscopy (AFM) in detail. XRD test indicates that this film is composed of V2O3, V3O5 and VO2.VO x microbolometer ...... hiện toàn bộ
Performance analysis of a hybrid OCDMA/WDM system
Frontiers of Optoelectronics - Tập 2 - Trang 15-20 - 2009
Hui Yan, Kun Qiu, Yun Ling
The performance of the hybrid optical code-division multiple-access (OCDMA) and wavelength division multiplexing (WDM) network is analyzed. End-to-end bit error rate (BER) of the network adopting error correction coding is calculated, and the expressions which show spectral efficiency performance, including the effects of polarization mode dispersion (PMD), are derived. The result demonstrates tha...... hiện toàn bộ
Laser detection by electronic instead of optical heterodyne using a two-frequency laser
Frontiers of Optoelectronics - Tập 1 - Trang 237-240 - 2009
Lei Li, Changming Zhao, Suhui Yang
A laser ranging system using a two-frequency laser is demonstrated, and the lidar-radar concept is introduced. A laser beam carrying 100 MHz radio frequency is obtained by a monolithic nonplanar ring single-frequency oscillator and an acousto-optical modulator, which is used as the light source of the two-frequency detecting experimental setup. With the optical transmitting and collecting system, ...... hiện toàn bộ
InAs/GaAs quantum dots grown on different GaAs substrates with graded In x Ga1 − x As strain-reducing layer
Frontiers of Optoelectronics - Tập 3 - Trang 241-244 - 2010
Shuping Fei, Zhongwei Shi, Lirong Huang
Self-assembled InAs quantum dots with graded composition strain-reducing layer (SRL) grown on exact substrates were studied. It is shown that a graded In x Ga1 − x As SRL leads to growth quality improvement, emission efficiency enhancement, and wavelength blueshift. Samples grown on 2° misoriented substrates with different In contents in gr...... hiện toàn bộ
