Abstract

Spirooxazines (SOs) and spiropyrans (SPs) are typical organic compounds exhibiting photochromism. Compared to SPs, SOs show better fatigue resistance and photostability, which provides a possibility of practical applications in lenses of variable optical density, displays, filters and optical-memory devices. The maximum values of photo-induced birefringence of spirooxazine in poly(methyl methacrylate) (PMMA) films pre-irradiated by ultraviolet light was investigated as a function of He-Ne laser (632.8nm) pumping-beam intensity. A dynamics of photo-induced birefringence was recorded by a linearly polarized double-frequency Nd:YAG laser (532 nm) of 0.1 mW as a probe beam. This material exhibited a competing process between photo-orientation and photo-isomerization. The photo-orientation is predominant when the power density of He-Ne beam is lower; while the photo-isomerization is dominant at relatively high power density of He-Ne beam. An improved phenomenological model, elucidating a competition between photo-orientation and photo-isomerization, was precisely presented. Dynamic holographic recording under linear polarized writing beams at 632.8 nm was performed on spirooxazine doped PMMA matrices assisted by UV light. It was found that dynamics of the optical storage signal intensity in the polymer films were dependent on the thermal stability and aggregation of spirooxazine molecules in PMMA matrices. A theoretical description the formation and eraser of the transient orientation grating, competing with isomerization gratings, agrees well with experimental results. The interaction between the chromophores and matrices was also discussed. It was indicated that spirooxazine-doped polymer films are candidates for reversible optical storage medium.
