Structure of fiber gratings directly written by infrared femtosecond laser

Amós Martínez, Mykhaylo Dubov, Igor Khrushchev, Ian Bennion

Research output: Chapter in Book/Published conference outputChapter


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.
