Assessment of optical bistability criteria in metal-insulator-metal plasmonic resonator containing Kerr nonlinear medium

Abstracts: In the current exploration, we numerically assessed the optical bistability occur criteria in a metalinsulator-metal structure that consists of two side coupled waveguides to a race-track-shaped resonator (RTSR). This particular RTSR contains a Kerr nonlinear material for filled medium. We happened to understand that any increase in the incident intensity, can cause a redshift for the resonance wavelength that is due to the refractive index shift induced by enhancing intensity. Moreover, the bistability loop that occurs within this RTSR could be a good candidate for application in any desired all-optical platform such as sensors, switches and analog-to-digital convertors and other integrated optical circuits.
