	Rearrangeable nonblocking 88 matrix optical switches based on extended banyan network (EI CONFERENCE) 会议论文 OAI收割作者: Zhang Y. 收藏 \| 浏览/下载：28/0 \| 提交时间：2013/03/25 Based on the CROSSBAR network (CN) and the BANYAN network (BN) 8 matrix optical switch two new rearrangeable nonblocking constructions of extended BANYAN network (EBN) are proposed for implementing 88 optical matrix switch. The interconnection characteristics of these two types of rearrangeable nonblocking EBN were studied optical insertion loss of 4.6 dB and the logic program for driving switching units was provided. The calculated insertion loss was 3.3 dB for 88 optical matrix switch. Silica waveguide 88 matrix optical switch was designed and fabricated according to the calculated results. The silica waveguide propagation loss of 0.1 dB/cm and waveguide-fiber coupling loss of 0.5dB/point were measured. With the fabricated 87times cross-talk of -38 dB polarization dependent loss of 0.4 dB averaged switching power of 1.6 W and switching time of 1 ms were achieved. A basic agreement between experimental results and theoretical calculated values was achieved.
	Optical fiber transmission of Q-switdied Nd:YAG pulses of 10MW peak power: Mechanism of damage to the fiber (EI CONFERENCE) 会议论文 OAI收割 2nd International Symposium on Advanced Optical Manufacturing and Testing Technologies - Advanced Optical Manufacturing and Testing Technologies, November 2, 2005 - November 5, 2005, Xian, China 作者: Wang L.; Zhang Y.; Chen W.; Tang Y.; Wang L. 收藏 \| 浏览/下载：30/0 \| 提交时间：2013/03/25 This paper presents theoretical analysis and experiment results of four different fibers transmitting 10MW peak power Nd: YAG laser pulse. The main factors limiting to optical fiber transmission of high power laser pulse is pointed including air breakdown at focus area and surface damage of optical fiber. The theory of air breakdown and the fiber coupling conditions is described briefly. The results of study to the transmission properties and damage conditions are presented on the basis of four different types of optical fibers. The results of the experiments are further analyzed in the aspects of transmitting efficiency air breakdown and surface damage. The local and foreign optical fibers with plastic-cladding and silica-cladding and step- index and graded- index fibers are tested separately in the experiments. The experiments showed that the imported fibers are able to transmit up to 10MW peak power laser pulse with no any visible damage while energy density at the fiber output end surface is 3.54GW/cm2. For local fibers damage on the input surface of both plastic-cladding and silica-cladding step-index fibers was found obviously. The column damage to the graded index fiber was also found and investigated in the research. Damage mechanisms of fiber at high peak power laser pulses are summarized. High quality finishing of fiber end surface will improve damage threshold tremendously. The conclusion of the study is that transmitting Q-switched Nd:YAG pulses of 10MW peak power is feasible for the domestically made fibers if their end surfaces are properly processed.
	Dispersion compensating properties of microstructure fiber (EI CONFERENCE) 会议论文 OAI收割 ICO20: Optical Communication, August 21, 2005 - August 26, 2005, Changshun, China 作者: Li C.; Wang W.; Wang W.; Li C.; Li C. 收藏 \| 浏览/下载：27/0 \| 提交时间：2013/03/25 Microstructure fiber is a new kind of optical fiber. An arrangement of air holes running along the full length of the fiber provides the confinement and guidance of light. The light is confined in the silica core along the fiber axis. This fiber has endlessly single mode special dispersion characteristics and so on. Using a vectorial effective-index numerical method we investigated the dispersion characteristics of a microstructure fiber with honeycomb cladding structures. The dispersion dispersion slope and Kappa parameter can be designed neatly by changing the air hole size and the separation of the holes in fiber cladding. We demonstrated the Microstructure fiber with large absolute value of normal dispersion and negative dispersion slope at the wavelength of 1550nm. Conventional communication non-shifted single-mode fibers and nonzero-dispersion shifted fibers (NZ-DSF) can be compensated efficiently using the microstructure fiber at the wavelength around 1550nm.
