Small, EarlyView.Supramolecular helicity meets ferroelectricity: P3HT‐b‐PMMA helical nanowires enable handedness‐specific modulation of remanent polarization in P(VDF‐TrFE) hybrids. This platform demonstrates the first CPL‐addressable ferroelectric PUF, translating molecular chirality into secure digital authentication.

Optical bistability in InP/GaInAsP equilateral-triangle-resonator microlasers
, 2009 Optical bistability is reported in InP/GaInAsP equilateral-triangle-resonator (ETR) microlasers, which are fabricated by planar technology. For a 30 mu m side ETR microlaser with a 2-mu m-wide output waveguide connected to one of the vertices of the ETR,

Optical bistability for two-level atoms in a standing-wave cavity [PDF]
, 1982 Observations of optical bistability are reported for a system composed of multiple atomic beams passing through a high-finesse optical cavity. Both the transmitted power and the intracavity fluorescent intensity have been re-corded as functions of ...

Controlling the optical bistability via interacting dark-state resonances
, 2010 We analyze the behavior of optical bistability in a four-level mercury atomic system driven by a cavity and two external coherent fields by means of a unidirectional ring cavity. We find that without interacting dark resonances and for large intensity of

Optical bistability in a low-photon-density regime [PDF]
, 2018 We give a microscopic description of the optical bistability, where the transmission coefficient has two different values as a function of input light intensity, and the system exhibits a discontinuous jump with a hysteresis loop.

Nonlinear properties of optical microfibres
, 2013 Glass microfibre waveguides offer an intriguing platform for the investigation of nonlinear effects, due to their high effective nonlinearity which arises from the tight modal confinement down to dimensions comparable to the wavelength of guided light ...

Small, EarlyView.A printable, reactivatable conductive adhesive (RCA) transitions from a robust, non‐tacky solid film into a soft, conformal biointerface upon solvent activation. By adapting to complex skin microtopography and hair‐covered scalp, the state‐programmable adhesive achieves strong adhesion and low interfacial impedance, enabling high‐fidelity EEG and pulse

Terahertz optical bistability of graphene-coated cylindrical core–shell nanoparticles
, 2018 In this study, we investigate the optical bistability of graphene-coated nanoparticles with cylindrical core–shell structure at terahertz frequency, because graphene displays optical bistability and multistability in a broad range of incident optical ...

Resonator-free optical bistability based on epsilon-near-zero mode [PDF]
, 2019 A majority of existing research on optical bistability rely on resonant schemes using nonlinear materials, which inevitably require a trade-off between the switching intensity and response time. In this work, we propose a novel non-resonant scheme, which
