When the feedback mechanism is provided by an internal procedure (not by an external entity like the mirror within the Interferometers), the latter will be known as intrinsic optical bistability.2 This process can be seen in nonlinear media containing the nanoparticles through which the effect of surface plasmon resonance can potentially occur.3
