Low threshold optical bistability based on coupled graphene Tamm states
The optical bistability based on an asymmetric dielectric Bragg reflector (DBR)–graphene–DBR (ADGD) structure is investigated numerically in terahertz frequencies. The threshold of optical bistability can be significantly reduced due to the strong enhancement of localized light field for the couplin...
