Development of new punctual optical fiber transducer for sensing

The international research community has been nurturing photonic technologies over the years, aiming to develop cost effective solutions for a number of applications. Optical fibers offer an efficient solution for sensing and communication fields. Fiber optic sensors present appealing characteristics that make them very attractive when compared with conventional electric sensors such as immunity to electromagnetic interferences, as well as unfavorable environments, small size, ability for multiplexing and remote sensing. Another important aspect when using optical fibers is the ability to simultaneously use them as sensors and communication channels. The primary motivation for this PhD work was the study and development of new structures based in photonic crystal fibers. The main idea was to take advantage of the know-how of our group in fiber-optic communications and photonic sensing, as well as the recent advances in the sensing area to develop new structures based on the platform of photonic crystal fibers.
