FAST OPTICAL SWITCH

A fast optical switch includes a pair of liquid crystal films disposed between two transparent substrates. Each liquid crystal film includes an antiferroelectric liquid crystal doped with a dichroic dye. The switch may have a response time of less than 1 millisecond. Un commutateur optique rapide co...

Zusammenfassung:	A fast optical switch includes a pair of liquid crystal films disposed between two transparent substrates. Each liquid crystal film includes an antiferroelectric liquid crystal doped with a dichroic dye. The switch may have a response time of less than 1 millisecond. Un commutateur optique rapide comprend une paire de films de cristaux liquides disposés entre deux substrats transparents. Chaque film de cristaux liquides comprend un cristal liquide antiferroélectrique dopé avec un colorant dichroïque. Le commutateur peut avoir un temps de réponse inférieur à 1 milliseconde.
