We show that the asymmetric configuration of QD-scatter system strongly impresses the amplitude and spectrum of quantum wire nanostructure transmission characteristics. It is shown that whenever the balanced number of chains-quantum dots in one molecule is substituted by unbalanced scheme, the number of forbidden mini-bands in quantum wire conductance increases to the sum of the number of quantum dots in two chains and thus the QW-nanostructure electronic conductance contains rich spectral properties due to appearance of the new anti-resonance and resonance points in spectrum. Considering the suitable inner gap between QD-chains in one molecule or outer gap between QD-molecules, can strengthen the amplitude of new resonant peaks in QW conductance spectrum. The proposed asymmetric-QD scatter system idea in this paper opens a new insight on designing quantum wire nanostructures for given electronic conductance.","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].

While phase shifting technique is widely applied for accurate and reliable static or semi-static phase measurement, Fourier and wavelet transforms are often employed for high speed dynamic phase measurement. In our previous papers, the authors had proposed an alternative clustering method for dynamic phase measurement. The proposed method utilizes the phase clustering effect and the prior knowledge of the speckle field to extract the deformed phase map from one single deformed speckle pattern. The clustering method, however, may fail at area with abundant noise and large phase gradient. In this paper, we improve the clustering method by incorporating an advanced phase filtering methods for wrapped phase filtering. The reconstructed wrapped phase map is with very good quality and ready for phase unwrapping with any simple unwrapping algorithms. The basic ideas and the implementation approach will be described in details. Several examples based on shearography and holographic interferometry will be presented. Comparisons between the proposed method and phase shifting method will be made. The results demonstrate the accuracy and robustness of the integrated dynamic phase extraction method. The integrated phase retrieval method proposed here has great potential to simplify optical setup for dynamic phase measurement.","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].

The idea is based on insertion of circular defect holes in the core area of an HF7 fiber. It is shown that by precisely adjusting the locations and the diameters of these defect holes, field distribution alters in a way that leads to a larger effective mode area than HF7 fiber itself. The validation of the proposed design is carried out by adopting an efficient full-vectorial finite difference frequency domain method with perfectly matched layers for accurate characterization of photonic crystal fibers. Dispersion characteristics of the designed fibers is also investigated and it is shown that the defect insertion has strong dispersion flattening and lowering attitude that can significantly ease the fiber design task for optical communication transmission systems.","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].

In particular, the air-gap distance between the disk and the SIL in the NFR system is less than 50 nm. Therefore, the disk and the SIL must be protected to detect the stable gap error signal (GES) during continuous control operation. In this manuscript, we propose an improved air-gap control system using a narrow-ban d disturbance filter (NBDF), which is an effective control method for enhancing the performance of the system for the rejection of repeatable and nonrepeatable disturbances In addition, we demonstrate an improved air-gap controller using a double disturbance observer (DOB) to improve the anti-shock control performance under external shocks. The double DOB uses a binomial Q filter without additional sensors, which keeps the production cost low. Finally, to evaluate the robustness of the control system with the double DOB, we apply a design method that varies the bandwidth of the Q filter.","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].
