Title: Optical fiber sensors engineered with femtosecond lasers

Abstract:

Femtosecond lasers have become a very powerful and convenient tool to fabricate micro-/nano- structures in different materials and waveguides. Based on refractive index modification, femtosecond laser inscription technique can directly fabricate a variety of structures such as gratings, interferometers and waveguides with great flexibility. In this talk, we will review our past and recent research work on the development of optical fiber sensors based on femtosecond laser inscription technique. We will discuss various kinds of micro-structures fabricated with femtosecond laser in optical fiber and demonstrated their applications as sensors for measuring different physical parameters.
