Low-threshold and high-extinction-ratio optical bistability within a graphene-based perfect absorber

HIGHLIGHTS

• who: Zhengzhuo Zhang et al. from the College of Advanced Interdisciplinary Studies and Hunan Provincial Key Laboratory of Novel Nano-Optoelectronic Information Materials and Devices, National University of Defense Technology, Changsha, China have published the article: Low-Threshold and High-Extinction-Ratio Optical Bistability within a Graphene-Based Perfect Absorber, in the Journal: Nanomaterials 2023, 389 of /2023/
• what: Most of the previous studies focus on the mid-IR to terahertz band since low-threshold OB could be achieved in those structures due to the strong field enhancement caused by the surface plasmons of graphene . . .
