Patent ID: 7238412

Claim:
An optical device comprising: a plurality of high index layers comprising high index degenerately doped materials; a plurality of low index layers comprising high thermal and electrically conductive materials, said low index layers are doped diamonds; and a mirror structure having alternating layers of said plurality of high index layers and said plurality of low index layers having a relationship E g,l >E g,h >hc/λ where E g,h is the band gap of a high index material used in said high index layers, E g,l is the band gap of a low index material used in said low index layers, λ is wavelength of light of interest, h is Plank constant, and c is the speed of light so that electricity and heat is conducted through said optical device, wherein the index difference between said plurality of high index layers and plurality of low index layers is greater than 0.3.
