Anisotropic Optical Properties of Thin-Film Thiacarbocyanine Dye Aggregates

Optical properties of thin films of aggregated thiacarbocyanine (TCC) dyes have been studied by means of spectroscopic ellipsometry and polarized IR spectroscopy. The experimental results reveal a strongly anisotropic response of the films, as quantified in the reported anisotropic dielectric functions over a wide range of frequencies. The studied TCC films exhibit both J-aggregate and H-aggreg...

Ultrafast polarization switching in thin-film ferroelectrics

We present an experimental approach to study the ultrafast polarization switching dynamics in thin-film ferroelectrics. A semiconductor photoconductive switch with femtosecond laser illumination is used as a ‘‘pulse generator’’ to produce jitter-free, sub-100 ps rise time step-function-like electrical pulses. Quantitative measurements yield a polarization switching time, ts , of ;220 ps when me...

Polarization-Conversion Guided Mode (PCGM) technique for exploring thin anisotropic surface layers.

A Polarization-Conversion Guided Mode (PCGM) technique has been developed to quantify optical anisotropy as low as 10-5 for a surface layer only 10 nm thick. The optical geometry consists of an index-fluid matched prism-coupler and an air-gap waveguide comprising the thin sample on a glass plate as the incident surface with a gold reflector forming the other surface of the guide. This allows no...

Optical constant of CoFeB thin film measured with interference enhancement method

Optical constants (n and k) of Co20Fe60B20 (CoFeB) thin films (2~40nm) are measured by using interference enhancement method with spectroscopic ellipsometry in the wavelength range of 270~1600nm. The effects of film thickness, protection layer and annealing process on the optical constant of CoFeB film are investigated. In the range of 40~10nm, both n and k decrease with the decrease of thickne...

Accurate Analysis of Polarization Coupling in Laminated Multilayered Thin Film Optical 3-D Waveguides

Coupled mode theory (CM) is widely applied in integrated optics, while the rigorous Local Mode theory (LM) is less known, being somewhat harder to implement. We compare the two theories in determining polarization coupling inside a laminated rib waveguide made of a-Si:H and SiO2.For moderate optical axis slant (low hybridization) and for fixed layer thickness the two theories show similar resul...
