Light emitting diodes include a silicon carbide substrate having first and second opposing faces, a diode region on the first face, anode and cathode contacts on the diode region opposite the silicon carbide substrate and a hybrid reflector on the silicon carbide substrate opposite the diode region. The hybrid reflector includes a transparent layer having an index of refraction that is lower than the silicon carbide substrate, and a reflective layer on the transparent layer, opposite the substrate. A die attach layer may be provided on the hybrid reflector, opposite the silicon carbide substrate. A barrier layer may be provided between the hybrid reflector and the die attach layer.
