Abstract

Modulator devices are selectably adjustable between at least two states, wherein the transmission and/or reflection of particular wavelengths of light are modified. Certain modulator devices are substantially uniformly adjustable over a wide range of wavelengths, including visible and infrared wavelengths. Other modulator devices are adjustable over visible wavelengths without significantly affecting infrared wavelengths. In addition, the modulator devices may be used in conjunction with fixed thin film reflective structures.
