摘要：A polarizing beam splitter （PBS） design based on a fused-silica lamellar subwavelength transmission grating is demonstrated with the modal method, where TE- and TM-polarized waves are mainly diffracted in the -1st and 0th orders, respectively. The physical explanation of the grating diffraction is illustrated by the interference of the corresponding parts of the two propagating modes, which is very similar to a Mach-Zehnder interferometer. It is shown that diffraction efficients over 99% for a TM-polarized wave in the -1st order and 90% for a TE-polarized wave in the 0th order are obtained at the wavelength of 1.053 μm. The polarization transmission extinction ratios are better than 33 dB and 51 dB for the order 0th and the -1st order, respectively. The splitting properties of the PBS grating designed by the modal method are in good agreement with the results simulated by the rigorous coupled wave analysis method.

摘要：With continuous technology scaling, on-chip structures are becoming more and more susceptible to soft errors. Architectural vulnerability factor （AVF） has been introduced to quantify the architectural vulnerability of on-chip structures to soft errors. Recent studies have found that designing soft error protection techniques with the awareness of AVF is greatly helpful to achieve a tradeoff between performance and reliability for several structures （i.e., issue queue, reorder buffer）. Cache is one of the most susceptible components to soft errors and is commonly protected with error correcting codes （ECC）. However, protecting caches closer to the processor （i.e., L1 data cache （LID）） using ECC could result in high overhead. Protecting caches without accurate knowledge of the vulnerability characteristics may lead to over-protection. Therefore, designing AVF-aware ECC is attractive for designers to balance among performance, power and reliability for cache, especially at early design stage. In this paper, we improve the methodology of cache AVF computation and develop a new AVF estimation framework, soft error reliability analysis based on SimpleScalar. Then we characterize dynamic vulnerability behavior of LID and detect the correlations between L1D AVF and various performance metrics. We propose to employ Bayesian additive regression trees to accurately model the variation of L1D AVF and to quantitatively explain the important effects of several key performance metrics on L1D AVF. Then, we employ bump hunting technique to reduce the complexity of L1D AVF prediction and extract some simple selecting rules based on several key performance metrics, thus enabling a simplified and fast estimation of L1D AVF. Based on the simplified and fast estimation of L1D AVF, intervals of high L1D AVF can be identified online, enabling us to develop the AVF-aware ECC technique to reduce the overhead of ECC. Experimental results show that compared with traditional ECC technique which

摘要：We introduce PBGFs with the cladding made of our newly designed quasi-hexagonal air holes and demonstrate how it actually operates. This cladding structure is introduced for the first time to the best of our knowledge, and is realized by making use of the hydrofluoric acid＇s corrosive properties. The fibre corrosion can be accurately controlled, thus opening us the gate for the design and fabrication of new PB. GFs with more complex and more efficient cladding structures. Numerical results and actual simulations indicate that PBGFs built with this cladding structure have improved b^dgap properties and guiding bands as wide as 500 nm have been theoretically reached. Using the same method, we have also been able to design two other types of PBGFs with improved cladding structure.

摘要：On the basis of single factor tests, the effect of trace elements—Fe2+, Co2+ and Ni2+ ions—on biological methane production from heavy oil was investigated by the response surface method. A three-level Box-Behnken design was employed to study the relationship between the independent variables and the dependent variable by applying initial Fe2+, Co2+ and Ni2+ concentration as the independent variables(factors) and using the methane production after 270 days of cultivation as the dependent variable(response). A prediction model of quadramatic polynomial regression equation was obtained. The results showed that the methane production could be as high as 240.69 μmol after optimization compared with 235.74 μmol obtained under un-optimized condition. Furthermore, the microbial communities before and after biodegradation were analyzed by PCR-DGGE method. The dominant bands were recovered and sequenced. Three strains were obtained; the strain T1 has 97% similarity with Bacillus thermoamylovorans, the strain H3 has 97% similarity with Bacillus thermoamylovorans and the strain H4 has 99% similarity with Bacillus vietnamensis.

摘要：A novel design of nearly zero dispersion flattened photonic crystal fiber （PCF） with double cladding is proposed. To employ traditional stack and draw technology, the cladding is composed of a traditional triangular lattice of air-holes and silica. The dispersion of the fiber is mainly engineered by the small air holes in the inner cladding, which are easily preserved in the fiber drawing procedure. The large air-holes in the outer cladding are mainly for light confinement. Thus, the dispersion property of the PCF is insensitive to the deformation of the air holes in the outer cladding. Using 8 layers of air-hole ring, the loss of the fundamental mode for the PCF is as low as 0.13dB/km at 1.55μm. The dispersion of the PCF fluctuates from -0.023 to 0.021ps·km^-1nm^-1 in the range 1.45-1.625 μm.
