Bandwidth-Engineered Ultra-Fast Time-Variant Metasurfaces

Abstract

Time-variant metasurfaces [1] have recently provided an ultra-fast approach to manipulating the optical response compared with conventional tunable approaches, like thermal and electric tuning. They allow for femtosecond scale switching by tuning under high-energy pumping sources. However, despite the recent advances in this field, the ability to precisely tailor the metasurface bandwidth with ultra-fast time response has not been carefully explored. Show more
