Abstract:
A transmissive optical device comprising: a layer ( 10 ) of light absorber material in the solid state, preferably made of a phase-change material with switchable refractive index such as GeSbTe; a partially-reflective layer ( 12 ), and a spacer layer ( 14 ) between the layer ( 10 ) of light absorber material and the partially-reflective layer ( 12 ). The spacer layer ( 14 ) and an optional cover layer ( 16 ) may be transparent conductive ITO layers which may serve to electrically switch the phase of the phase-change material layer ( 10 ), thereby switching the transmission/reflection properties of the transmissive optical device.

Claim (Index 10):
A device according to  claim 1 , wherein the light absorber material is a phase-change material having a refractive index that is settable to at least two values which confer different optical transmission properties to the device.
