Zusammenfassung:	OPTICAL SWITCHING DEVICES An optical switch, eg. a blocking switch or a coupler switch, has a liquid crystal control element which, in at least one of its control configurations, has a splayed molecular orientation. In a preferred embodiment the liquid crystal is surrounded by chemical control surfaces, eg. by homeotropically coated control surfaces.
