CHANGES IN REFRACTIVE INDEX OF STANDARD TELECOMMUNICATION FIBER THROUGH EXPOSURE TO FEMTOSECOND LASER PULSES AT 810 nm

Not Accessible

Your library or personal account may give you access

Abstract

Permanent refractive index changes as large as 6.10-3 in standard fibers is obtained by means of irradiation with tightly focused femtosecond near-infrared pulses. The dependence of the index variation with the exposure time is depicted.
