	DVI interface, optical fiber video transceiver used in LED display system (EI CONFERENCE) 会议论文 OAI收割 2011 IEEE 3rd International Conference on Communication Software and Networks, ICCSN 2011, May 27, 2011 - May 29, 2011, Xi'an, China 作者: Wang R.; Li S. 收藏 \| 浏览/下载：29/0 \| 提交时间：2013/03/25 A professional DVI-Video optical fiber transceiver was designed based on FPGA (Field Programmable Gate Array) in order to meet the need of real-time LED display. The system could be used to transmit a non-loss real-time video source whose resolution was 1024 768 and refresh rate was 60Hz in a single mode optical fiber. The top-down design method was used while programming FPGA. Some module design ideas were discussed including video data acquisition caching framing frame detecting and video reproducing. The required bandwidth of each module was analyzed and calculated in details. Some relevant simulation results were also given. In practical test real-time video display was achieved. And the transmission rate of coded data was up to 2Gbps and the transmission distance could reach 10km. 2011 IEEE.
	All fiber ytterbium-doped fiber grating laser (EI CONFERENCE) 会议论文 OAI收割 High-Power Lasers and Applications III, November 8, 2004 - November 11, 2004, Beijing, China 作者: Zhang L.; Wang L.; Wang L.; Wang L.; Ning Y.-Q. 收藏 \| 浏览/下载：22/0 \| 提交时间：2013/03/25 Based on requirement of all fiber structure all fiber Yb-doped fiber grating laser uses double cladding fiber with Yb-doped as gain medium uses fiber grating as resonance cavity and employs semiconductor laser as pumping source to realize the lasing based on the reverse of Yb ion. We use Bragg fiber grating as the resonance cavity of fiber laser and 970nm LD as pumping source pump the Yb-doped double cladding fiber with circular inner-cladding. We realized 7.5 W single-mode laser output central wavelength of 1080nm FWHM of 0.11 nm under the pump power of 11.8W. Maxim conversion efficiency is 63.5 % and slope efficiency of 46.4%.
	Numerical analysis and experimental research of output performance for Yb3+-doped double-clad fiber lasers (EI CONFERENCE) 会议论文 OAI收割 High-Power Lasers and Applications III, November 8, 2004 - November 11, 2004, Beijing, China 作者: Wang G.; Gao Y.; Li Y.; Li Y.; Li Y. 收藏 \| 浏览/下载：16/0 \| 提交时间：2013/03/25 In this paper numerical analysis was investigated for the double-clad fiber lasers and experimental study on the Yb3+-doped double-clad fiber lasers was performed. The results shown that the output power increased monotonically with absorbed power and in lossy cavity the output power is less than in the lossless cavity. The output power decreases for the lossy fiber with the reflectivity of output coupler. There was an optimum fiber length to reach a maximum output and the optimum length was mainly dependent on the loss coefficient. In experiment we obtained a output power of 21.6W slope efficiency of 54% by using Yb3+-doped double-clad fiber and 40W LD pump source.
