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 ...
