Ultrafast laser filamentation results from the interaction of ultrafast laser with Kerr media.
During filamentary propagation, the transparent medium is altered by numerous linear and …

Vibration monitoring of rotating machinery is crucial for operational safety and optimized
maintenance. In this work, we propose a fiber Bragg grating (FBG) vibration sensor that does …

The direct femtosecond laser inscription method is very competitive in the fabrication of fiber
Bragg gratings, but its refractive index modification region is very limited and leads to low …

The optical fiber sensing field is in continuous seek of new processing methods, light
localization structures and transduction mechanisms for developing devices with novel …

In this thesis, femtosecond laser writing is harnessed towards advancing capabilities in the
fabrication of novel fiber Bragg grating based sensors. Femtosecond laser pulses inscribed …

Miniaturizing optical components has been a dominant research theme for the past few
decades [1]. However, such miniaturization is no guarantee for the reduction of the overall …
