We report a highly sensitive refractive index sensor based on a looped micro-deformed tapered fiber. The micro-deformation is induced by first shaping the taper into a loop, and then, a ball-shaped fiber end bends the taper waist. While the tapered f

A study of the effect on the coupling efficiency due to surrounding refractive index and fusion depth variations in (1+1) side-pump combiners is presented. The external refractive index values used in the simulations are 1.0 and 1.35, which correspon

The main contribution of this work is the multiplane measurement of temperature fields of fluid flows. We use a focusing schlieren system to fulfill such an objective. The optical system contains a color digital camera, an RGB off-axis illumination,

The simultaneous measurement of the numerical aperture (NA) and mode field diameter (MFD) of single-mode fibers was performed on several commercial fibers by means of digital image processing of the output light projected into a screen. In addition,

A multimode optical fiber scrambler (MOFS) based on an asymmetric taper is demonstrated. The MOFS contains an adiabatic down-taper transition and an abrupt up-taper transition made into a double cladding fiber. This device improves the pump power abs

A method for measuring planar temperature fields of fluid flows is proposed. The focusing schlieren technique together with a calibration procedure to fulfill such a purpose is used. The focusing schlieren technique uses an off-axis circular illumina

In this work, we have developed a procedure for full-field measurement of temperature of a fluid flow by using the schlieren technique. The basic idea is to relate the intensity level of each pixel in a schlieren image to the corresponding knife-edge
