Abstract :
In view of POLICRYPS (an acronym for polymer-liquid crystal-polymer slices) optimisation, this study analyses the dynamical response of POLICRYPS gratings and its relation with some geometrical and morphological factors. The final goal is to get overall response times in the sub-millisecond range. Results show that even for not-optimised grating samples, it was possible to get simultaneously both rise and fall response times in the range 50-150 μs by means of a proper choice of the driving pulse shape. These results are very attractive for many possible applications in telecom devices.
