OPTICAL STUDIES OF COLORED CHEMICAL SPECIES
Evanescent wave spectroscopy using thin optically transparent electrodes and multiple reflections allows unique observations of the electrochemical interphase since the region of solution sampled is typically 100 nm from the electrode in the visible spectral region. This technique is found to be highly sensitive to the presence of absorbing adsorbed species
متن کاملComparative numerical studies of ion traps with integrated optical cavities
We study a range of radio-frequency ion trap geometries and investigate the effect of integrating dielectric cavity mirrors on their trapping potential using numerical modelling. We compare five different ion trap geometries with the aim to identify ion trap and cavity configurations that are best suited for achieving small cavity volumes and thus large ion-photon coupling as required for scala...
متن کاملFemtosecond Dephasing Studies of Dye Molecules in a Polymer Host
The optical dephasing properties of molecular impurities in low-temperature amorphous solids have been extensively studied in recent years as a means of probing the host environment. Non-linear optical frequency domain techniques, such as fluorescence line narrowing [l]_ photochemical [2,3] and non-photochemical [4,5] hole burning, resonant Rayleigh scattering [6] and polarization spectroscopy ...
متن کاملPure optical dephasing dynamics in semiconducting single-walled carbon nanotubes.
We report a detailed study of ultrafast exciton dephasing processes in semiconducting single-walled carbon nanotubes employing a sample highly enriched in a single tube species, the (6,5) tube. Systematic measurements of femtosecond pump-probe, two-pulse photon echo, and three-pulse photon echo peak shift over a broad range of excitation intensities and lattice temperature (from 4.4 to 292 K) e...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
