Structure of fiber gratings directly written by infrared femtosecond laser


Structural modification m gratings inscribed point-by-point by a femtosecond laser is investigated using quantitative phase microscopy. The gratings present a central region with a depressed refractive index surrounded by an outer corona with increased index. © 2006 Optical Society of America.
