From: Resonator-free optical bistability based on epsilon-near-zero mode
Optical bistability curves and temporal response based on ENZ mode for various device length (l). (a,b) optical bistability curves for l = 500 nm and l = 1 µm, respectively. (c,d) temporal response of bistability for l = 500 nm and l = 1 µm, respectively. The blue dot denotes input intensity with the variation of P1 → P2→ P1* → P3 → P1 indicated in (a), and the red line denotes corresponding output intensity.
