Fabrication of channel waveguides in dye-doped polymer films by a beam-processing machine based on photo induced bleaching.

Applied optics

Azari A, Mohajerani E, Abedi Z, Eslami Z.
PMID: 24216576
Appl Opt. 2013 Oct 20;52(30):7228-32. doi: 10.1364/AO.52.007228.

Irreversible changes in the refractive index of a dye-doped polymer film by photo induced bleaching were measured with a Mach-Zehnder interferometer. The decrease in the refractive index of the film for various laser powers and various radiation times has...

BACKGROUND: Heart transplant surgeries using cardiopulmonary bypass (CPB) typically requires mechanical ventilation in intensive care units (ICU) in post-operation period. Ultra fast-track extubation (UFE) have been described in patients undergoing various cardiac surgeries.AIM: To determine the possibility of ultra-fast-track...

Ultrason Sonochem. 2009 Jan;16(1):11-4. doi: 10.1016/j.ultsonch.2008.05.011. Epub 2008 Jul 07.

Cauliflower-like ZnO nanostructures with average crystallite size of about 55 nm which have surface one dimensional (1D) nanoarrays with 10 nm diameter were successfully fabricated through a simple sonochemical route. X-ray diffractometry (XRD), scanning electron microscopy (SEM), transmission electron...

Interferometry technique to eliminate noise in interference data based on a Mach-Zehnder interferometer.

Applied optics

PMID: 24663448
Appl Opt. 2014 Mar 20;53(9):1734-8. doi: 10.1364/AO.53.001734.

Some experiments based on interferometry, such as studying refractive index changes, need a long time to be completed, and any movement or oscillation in the order of wavelength during that time may wash out the interference fringes or at...
