The optical switch is a crucial component in optical communications that plays an important role in transmitting the optical signal within a photonic circuit. In this paper, an all-optical plasmonic switch composed of five nanodisks made from gold, planted inside SiO2 substrate, based on Fano resonance, has been proposed. The simulation results disclose that the structure can work as an infrared optical switch by adjusting the pump light at 825 nm wavelength. The occurrence of the second Fano resonance (FR) due to the reduction in the distance between nanodisks was reviewed. The two-dimensional simulations using the finite-difference time-domain algorithm are utilized to reveal apparent optical bistability and notable switching mechanism of the signal light. The results show -4.00 dB and -36.84 dB transmissions when the pump is OFF and ON, respectively. As known, in highly integrated optical communication, ultrasmall all-optical switches are of great importance. This switch has a nanoscale size of 450 nmx450 nm.

In this work, an ultra-fast all-optical plasmon induced transparency based on a metal-insulator-metal nanoplasmonic waveguide with two Kerr nonlinear ring resonators is studied. Two-dimensional simulations utilizing the finite-difference time-domain method are used to show an obvious optical bistability and significant switching mechanisms of the signal light by varying the pump-light intensity. The proposed all-optical switching based on plasmon induced transparency demonstrates femtosecond-scale feedback time (90 fs), meaning ultra-fast switching can be achieved. The presented all-optical switch may have potential significant applications in integrated optical circuits.
