This theoretical study has been carried out on the characteristics of light–plasmon coupling on the chiral–graphene interface. The graphene’s conductivity is modeled in the framework of Kubo’s formulism. The impedance boundary condition approach is used to compute the dispersion relationship for the chiral–graphene interface and dispersion curve analysis is used to study the light–plasmon coupling on the chiral–graphene interface. This study concludes that the chiral–graphene interface supports the hybrid surface plasmon modes, i.e., the upper and lower modes that can be used to sense the chirality and chemical sense biochemical molecules. Furthermore, this study presents the influence of chirality (), chemical potential (), and layers of graphene () on the dispersion relation, propagation length (), and effective mode index (), and it concludes that both the chiral and graphene parameters can be used to tune the plasmonics resonance frequencies. This study presents the cutoff chiral value () as a function of the frequency () under different values of chemical potential () and index of refraction (), and the numerical results revealed that light–plasmon coupled modes are exploitable for on-chip chiral sensing and enantiomeric detection applications.
