Femtosecond-Laser Patterning of Polymers: Nonlinear and Negative Index Devices
Abstract
The research described in this report focused on expanding our knowledge of laser micromaching and the scope of femtosecond laser fabrication. The research addressed Army Research Office initiatives for the development of novel photonics devices and techniques that utilize nonlinear optical phenomena. The interaction of femtosecond laser pulses with polymers were studied and the conditions for device fabrication were optimized. Various ways for inducing nonlinear response in polymers devices were investigated. The work allowed the group to expand its investigation of femtosecond laser interactions with materials to polymers and create polymer-based photonic devices. The applications of research may extend into other fields, including medicine and engineering. Femtosecond laser pulses were also used to study ultrafast dynamics in solids, such as zinc oxide, through pump probe experiments. The transient material properties obtained through such experiments can be used to optimize ZnO-based devices. Other dielectric materials, including fused silica and diamond were micromachined and studied under irradiation from femtosecond laser pulses.
