“…ptical bistability (OB) is characterized by an S-shaped hysteresis loop [1] and catches a widespread attention due to its intriguing applications in optical switching [2] , optical storage [3] and optical diode [4] . Different from the external stimuli (such as the magneto-optical effect [5] and the electro-optic effect [6] ), the all-optical bistability is an internal stimulus scheme, where a Kerr nonlinear medium or an absorber is utilized to induce a positive feedback and therefore the electronic bottleneck can be excellently avoided.…”

Owing to an additional thinner planar waveguide with micron scale is attracted to the symmetrical metal cladding waveguide (SMCW) with sub-millimeter scale, the interference interaction between different Q-value guided modes would generate a Fano reflectivity curve. In our double metal-dielectricmetal waveguides (DMDMW) structure, a Kerr nonlinear medium is located in the guiding layer of the SMCW where the excited oscillating wave is enormously enhanced. Numerical calculations show that a minute variation of the incident light intensity will give rise to a change in the dielectric constant of the Kerr nonlinear medium and lead to positive feedback. A bistable reflection can be achieved with a low threshold and a large modulation depth because of the sharpness and the asymmetricity of the Fano reflectivity curve.

“…Optical bistability, which is characterized by an S-shaped hysteresis loop, allows two stable outputs for one single input and offers many intriguing applications, such as all-optical switchings, [1,2] optical memories, [3] and optical diodes. [4] There are two critical factors to realize the bistability, one is a resonant behavior and the other is positive feedback. To satisfy the latter critical factor, various proposed schemes draw support from the external stimuli, including the electro-optic effect, [5] and the magneto-optic effect.…”

Owing to the enormously enhanced oscillating wave, a minute variation of the incident light intensity will give rise to a change in the dielectric constant of the Kerr nonlinear medium and lead to a bistable reflection with an ultra-low threshold intensity, which is closely related to the angle of incidence and the thickness of the Kerr nonlinear medium. The criterion for the existence of optical bistability is derived. Our bistability scheme is simple and not limited to the TM-polarization.
