Measurement of thin film parameters with a prism coupler.
نویسندگان
چکیده
The prism coupler, known from experiments on integrated optics, can be used to determine the refractive index and the thickness of a light-guiding thin film. Both parameters are obtained simultaneously and with good accuracy by measuring the coupling angles at the prism and fitting them by a theoretical dispersion curve. The fundamentals and limitations. of this method are discussed, its practical use, and mathematical procedures for the evaluation.

Determination of refractive index, thickness, and the optical losses of thin films from prism-film coupling measurements.
We present a method of analysis of prism-film coupler spectroscopy based on the use of transfer matrix and genetic algorithm, which allows the simultaneous determination of refractive index, thickness, and optical losses of the measured layer.
متن کاملSingle-arm double-mode double-order planar waveguide interferometric sensor.
A sensor is described for which interference measurements of the phase delay between two propagating modes of different orders in a slab thin-film waveguide are used as the sensing technique. The basic building block of the sensor is a polymer film doped with an indicator dye such as Bromocresol Purple. The modes of two orders such as TM(0) and TM(1) are simultaneously excited in the light-guid...
متن کاملInvestigating properties of surfaces and thin films using microsphere whispering-gallery modes
We use a tunable diode laser operating near 1570 nm to investigate various effects of the heat transfer from fused-silica microspheres, with and without thin-film coatings, to the surrounding gas in a vacuum chamber. The resonance frequencies of microsphere whispering-gallery modes (WGMs), excited by a tapered-fiber coupler, shift with changing temperature (about -1.6 GHz/K at 1570 nm). This sh...
متن کاملA Novel Label-Free Optical Biosensor Using Synthetic Oligonucleotides from E. coli O157:H7: Elementary Sensitivity Tests
SiO(2)-TiO(2) thin films for use as fiber optic guiding layers of optical DNA biosensors were fabricated by the sol-gel dip coating technique. The chemical structure and the surface morphology of the films were characterized before immobilization. Single probe DNA strands were immobilized on the surface and the porosity of the films before the hybridization process was measured. Refractive inde...
متن کاملA study on the dependence of DC electrical properties and nanostructure of Cu thin films on film thickness
This paper reports the correlation between film thickness, nanostructure and DC electrical properties of copper thin films deposited by PVD method on glass substrate. X-ray diffraction (XRD) and atomic force microscopy (AFM) were used for crystallography and morphology investigation, respectively. Resistivity was measured by four point probe instrument, while a Hall effects measurement system w...
