Investigating the experimental limits of the Brewster’s angle method
We present the method, analysis, and experimental results of the Brewster’s angle method commonly used for determining the refractive indices of optical films. We show the significance of the intersection of reflectance ...
A practical approach for optical characterization of a film coated on the optical fiber
Phase Diffraction (PD) Phase Diffraction. which is a result of the interaction of light waves with a transparent object, is exploited to characterize precisely optical properties of dielectric films coated on the optical ...
Vector modal solution of evanescent coupler
We present a vector modal solution for the evanescent coupler comprising an optical fiber and a slab waveguide. We identify the normal vector ridge modes of the device for different configurations. The dispersion characteristics ...
An experimental work on optical component based on D-fiber/slab evanescent coupling structure
(Kluwer Academic Publishers, 2003-01)
Fiber/slab coupler structure has been exploited as a passive in-line optical fiber component for functions of filtering, intensity modulating and switching by many researchers. In this work a device based on the elliptic ...
Device length requirement in slab/fiber evanescent coupler
(Taylor & Francis, 2000)
The effective device lengths of the fiber half-coupler for various radii of curvatures was found. This calculated length was about a thousand times greater than that calculated by the model method. The device has enough ...
