Now, according to the present invention, multiple band optical reflectors
are provided that utilize a stack of metal and dielectric layers to
create a reflection curve in the visible spectrum that has multiple peak
intensities. Reflectors of the present invention comprise at least two
dielectric layers that have differing thicknesses, with metal layers
disposed therebetween. The use of metal layers in the present invention,
as opposed to using alternating layers of dielectric materials, results
in a reflector that is substantially thinner than a conventional two
dielectric reflector.
