Paper Abstract

Microstructuring of Polymer Optical Fibers-POF through surface modification with UV excimer laser radiation has been performed and studied. The laser modified surface cavities on fibers act as material receptors of exact volume allowing highly controllable and repeatable structures. The effect of Laser writing conditions on different etching characteristics of cladding and core materials of the fibres are presented. Ablated structures on the fibres are examined for optimised sensors' response characteristics. As a case study humidity and ammonia sensors are demonstrated by employing sensitive block copolymer materials on suitably micromachined segments of fibres.
