When certain molecules are doped into polymers, they are photo-chemically more stable to photodegradation than the
same molecule in liquid solution or crystalline form. Furthermore, such composite materials are also found to self heal
after photo-damage when they are stored in the dark. Repeated laser cycling of these dye-doped polymers make them
more immune to future photodegradation. In parallel, it has been observed that electrooptic devices made with poled
dye-doped polymers become more robust upon irradiation by gamma-rays. In the present work, we combine both
gamma radiation and laser cycling and find that the synergism between the two processes may result in more robust
We report on a procedure to fabricate a specific micro-structured fiber with metal wires array running down its length. The goal is to develop an unique photonic bandgap lattices with enhanced optical nonlinearity. Mechanism of enhanced nonlinearity is briefly discussed. FDTD simulation on single-wire fiber is presented.
