The unique characteristics of ultrafast lasers, such as picosecond and femtosecond lasers,
have opened up new avenues in materials processing that employ ultrashort pulse widths …

Because of their small size, passive nature, immunity to electromagnetic interference, and
capability to directly measure physical parameters such as temperature and strain, fiber …

Fiber Bragg grating (FBG) is the most widely used optical fiber sensor due to its compact
size, high sensitivity, and easiness for multiplexing. Conventional FBGs fabricated by using …

Femtosecond laser micromachining can be used either to remove materials or to change a
material's properties, and can be applied to both absorptive and transparent substances …

In this paper we review the micromachining of photonic devices in several materials by
means of ultrashort laser pulses. The physical mechanisms underlying the refractive index …

In this article, we review recent advances in the technology of writing fiber Bragg gratings
(FBGs) in selected cores of multicore fibers (MCFs) by using femtosecond laser pulses. The …
