Abstract

We performed detailed characterizations of the transient nematic effect in parallel aligned nematic liquid crystal cells and adapted this technique to blazed phase gratings operating in the 1.55 micrometers telecommunication window. With reflective cells, on/off response times lower than 50 and 2 ms, respectively, have been observed with an appropriate design of the voltage sequences applied to the different electrodes.
