This talk will cover our past and ongoing work on light-sensitive and tunable optical devices for sensor protection and imaging in the mid-infrared spectral range. These devices use phase-transition materials, especially vanadium dioxide, as tunable and light-sensitive elements that can be integrated with micro/nanophotonic structures. I will present optical diodes that feature asymmetric transmission, limiters based on frequency-selective surfaces, and temperature-tunable spectral filters based on thin-film stacks.
