Optical fibers have many advance and exciting applications, in particular optical
telecommunication and sensing. These applications are depending basically on the fiber …

We report, for the first time, the use of a fiber optic Mach-Zehnder interferometer to measure
core refractive index changes written by an ultrafast laser irradiation. The core-offset …

A method for measuring the refractive index of low-transparent crude oils using a capillary
tube interferometer is described. The method is based on analyzing the resulting transverse …

A novel transmitted-light differential interference contrast (DIC) system is used for
nondestructive measurement of the refractive-index profile (RIP) of an optical fiber. By …

A new technique (El-Ghandoor et al., Opt. Laser Technol. 31 (7)(1999) 481–488) has been
applied to study the shape of transverse interference fringes, instead of multiple beam …

The formula of refractive index of fiber considering the refraction has been reviewed. This
formula is used to investigate the effect of refraction on the accuracy of refractive index …

A fusion-spliced optical fiber is examined with a laser sheet of light. A CCD camera is used
to record the transverse interference pattern from the fiber. The buckling on the fiber material …

We present a method for determining the refractive-index profile of polymer optical fiber
preforms through a direct-deflection measurement. The method is simple to use, compact …

In this research, we have studied the interaction between femtosecond laser and dielectric
material, especially borosilicate glass, and its applications. Using laser direct writing (LDW) …

The development of reliable, affordable, and efficient sensors is a key step forward in
providing tools for efficient monitoring of critical environmental parameters. Fiber-optic …
