Web6. júl 2024 · For example, AlN and AlGaN have a maximum refractive index contrast in the range 7–11%. An AlN/AlGaN DBR structure has achieved 97% reflectivity down to 220–250 nm, but required 30.5 pairs [ 5 ]. Alternatively, a much higher refractive index contrast can be achieved with layers of the same lattice constant by creating porosity in doped layers.
