Claim 5:
6. The optical device of claim 1, wherein the ORRS (100) is selected from:
(a) a resonant grating structure with the conversion layer (104) being a liquid crystal layer;
(b) a guided-mode resonant grating structure with the conversion layer (104) being a liquid crystal layer;
(c) a guided-mode resonant structure with the conversion layer (104) being a helical liquid crystal with the helix axis laying in the plane of the substrates (60);
(d) a guided-mode resonant structure with the conversion layer (104) being a helical liquid crystal with the helix axis titled from the plane of the substrates (60);
(e) a multi-layered structure made of porous silicon layers;
(f) a porous structure infiltrated with the conversion layer (104), wherein said conversion layer (104) is a liquid crystal layer;
(g) a photonic crystal structure integrated with the conversion layer (104), wherein said conversion layer (104) is a liquid crystal layer;
(h) a periodic liquid crystal structure configured to exhibit selective reflection peaks;
(i) a multi-layered structure, further comprising at least one of the layers selected from an absorptive layer, a coupling layer and a waveguide layer configured to excite a broadband lossy mode or a Fano resonance;
(j) a cavity structure, such as a Fabry-Perot etalon, filled with the conversion layer (104), wherein said conversion layer (104) is a liquid crystal layer exhibiting at least one dip in reflection in the visible range; and
(k) a plasmonic structure exhibiting at least one dip in reflection.
