Volume hologram recording in diarylethene doped polymer

摘要

Volume holographic properties of diarylethene doped polymers are reported for the first time. Resolution of more than 1500 lines/mm with Δn about 10~(-4) is demonstrated on a sample 1 mm thick. Angular selectivity contains two contributions - the wide one from the amplitude holographic component, and the sharp one from the phase counterpart. The half-width of the amplitude component is about order of magnitude larger than that of the phase component. High fatigue resistance of the dye allows multiple record/erase cycles without degradation. Thermal stability of the dye allows for durability of the recording material at the temperatures above 115 ℃. Holograms while stable at room temperature exhibit thermal degradation at elevated temperatures even below 115 ℃. This gives potential to implement on that material multiple use holographic thermal sensors.
