Abstract:
A liquid crystal Fabry-Perot etalon comprising:a first substrate coated on a first side with a first transparent conductor layer; a first reflector layer disposed over the first transparent conductor layer on the first side of the first substrate; an alignment layer disposed over the first transparent conductor layer on the first side of the first substrate; a spacer plate coated on a first side with a second transparent conductor layer, the first side of the spacer plate facing the first side of the first substrate, the spacer plate having a second side opposite its first side; plural spacers disposed between the first substrate and the spacer plate to define a predetermined gap between the first substrate and the spacer plate; liquid crystal filled in between the first substrate and the spacer plate; and a second substrate coated on a first side with a second reflector layer, the first side of the second substrate facing the second side of the spacer plate; wherein the second substrate is spaced a predetermined distance apart from the spacer plate.
