Claim:
1. An optical device, comprising: a substrate including an active region, that is reachable by an incident light on the device, having a refractive index greater than 1; an electrode in operative contact with the substrate, wherein said electrode has at most two broadband, specularly-reflecting surfaces disposed to receive broadband incident light, wherein each of the at most two surfaces are inclined at a different angle with respect to a horizontal reference, such that substantially all of the broadband light incident on each surface is specularly reflected therefrom; and a cover layer covering at least a portion of the top surface of the substrate including the electrode, and within which cover layer the electrode is disposed, wherein substantially all of the broadband light incident on each of the at most two specularly-reflecting surfaces will be incident upon the cover layer and reflected therefrom at an angle, θ, where θ will be sufficient for total internal reflection (TIR) of substantially all of the light from the cover layer and directed to the active region of the substrate.
