Abstract
Doping-tunable mid-infrared extraordinary transmission is demonstrated from a periodic metal hole array patterned on n-InSb. The polarization-dependent transmission was measured at room temperature and 77 K. In addition, the extraordinary transmission was measured for incident angles from 0° to 35° in 5° steps, A fundamental resonance shift of ∼123 cm -1 (1.4 u.m) is observed by varying the doping from 1 × 10 16 to 2 × 1018 cm-3. The calculated transmission resonances were in good agreement with the experimental results. This suggests that InSb semiconductor-based plasmonic structures may be suitable for a variety of tunable mid-infrared device applications.
