A universal and stable metasurface for photonic quasi bound state in continuum coupled with two dimensional semiconductors

Abstract The strong coupling of excitons to optical cavity modes is immense importance when understanding the fundamental physics quantum electrodynamics at nanoscale as well for practical applications in information technologies. There have been several attempts achieving between two-dimensional semiconductors, such transition metal dichalcogenides (TMDCs) and photonic quasi-bound states continuum (BICs). We identify two gaps platforms TMDC quasi-BICs: firstly, studies so far, different architectures employed TMDCs. This would mean that typically, fabrication process flow cavities will need be modified one moves from other, which can limit technological progress field. Secondly, there has no discussion impact imperfections on these subsystems far. In this work, we address questions by optimizing a with same architecture, couple four typical TMDCs (MoS 2 , WS MoSe WSe ) perform detailed investigation tolerance associated quasi-BICs their coupling.
