Optical bistability via an external control field in all-fiber ring cavity [PDF]

open access: yesScientific Reports, 2017
We demonstrate a new scheme for realizing the Optical Bistability (OB) inside an all-fiber ring cavity with an external control field. In the absence of the external control field, the pump power is fixed below the threshold value of laser, and there is ...

Microwatt Volatile Optical Bistability via Nanomechanical Nonlinearity [PDF]

open access: yesAdvanced Science, 2023
Metastable optically controlled devices (optical flip‐flops) are needed in data storage, signal processing, and displays. Although nonvolatile memory relying on phase transitions in chalcogenide glasses has been widely used for optical data storage ...

Terahertz Optical Bistability in the Metal Nanoparticles-Graphene Nanodisks-Quantum Dots Hybrid Systems [PDF]

open access: yesNanomaterials, 2020
We theoretically investigate the optical bistability in the metal nanoparticles-graphene nanodisks-quantum dots hybrid plasmonic system in the infrared regime of the electromagnetic radiation. The quantum dot is considered to be a three-level atomic-like

Broadband and Ultra-Low Threshold Optical Bistability in Guided-Mode Resonance Grating Nanostructures of Quasi-Bound States in the Continuum [PDF]

open access: yesNanomaterials, 2021
We model optical bistability in all-dielectric guide-mode resonance grating (GMR) nanostructures working at quasi-bound states in the continuum (BICs). The complementary metal-oxide-semiconductor (CMOS) compatible material silicon nitride (SiN) is used ...

Intrinsic optical bistability via switching between saturable and reverse saturable absorption [PDF]

open access: yesScientific Reports
We present a novel approach to achieving intrinsic optical bistability and multistability through the interplay between saturable and reverse saturable absorption. Our findings reveal that the stable points on the optical bistability curve align with the
