Tunable mid-infrared refractive index sensor with high angular sensitivity and ultra-high figure-of-merit based on Dirac semimetal

A tunable mid-infrared refractive index sensor consisting of bulk-Dirac-semimetal (BDS) and one-dimensional photonic crystals (1DPC) is proposed. This sensor has high angular sensitivity and ultra-high figure-of-merit (FOM), which is attributed to the optical Tamm states excited at the interfaces be...
