Tunable mid-infrared photonics
Time: 10:00 am
Place: 5310 Chamberlin Hall
Speaker: Mikhail Kats
Abstract: The mid-infrared (mid-IR) spectral range (wavelengths from ~ 2 μm to ~20 μm) has recently become more important for both applications and fundamental science. However, compared to their counterparts in the visible, optical components in the mid-IR are still significantly under-developed.
We create tunable optical components for the mid-IR by incorporating materials that respond to temperature, current, or applied electric field into photonic structures such as interference coatings and optical metasurfaces. In particular, we exploited the insulator-to-metal phase transition of vanadium dioxide (VO2) to create temperature- and current-tunable modulators and thermal emitters, and used electrostatic doping in graphene to construct reconfigurable metasurfaces that operate at nanosecond time scales.
