Optical and Thermal Properties of a Hybrid Metal–Dielectric Reflector

The thermal and optical properties of a combined (hybrid) metal–dielectric reflector comprising a gold layer and distributed Bragg reflector composed of alternating In0.52Al0.48As/In0.53Ga0.47As bilayers are considered. It is established that a high coefficient of reflection of the hybrid structure can be achieved at low absorption in the metal and relatively small total thickness of the dielectric reflector.
