Dynamic optical bistability in resonantly enhanced Raman generation
, 2004 We report observations of novel dynamic behavior in resonantly-enhanced stimulated Raman scattering in Rb vapor. In particular, we demonstrate a dynamic hysteresis of the Raman scattered optical field in response to changes of the drive laser field ...

Cavity Nonlinear Optics at Low Photon Numbers from Collective Atomic Motion
, 2007 We report on Kerr nonlinearity and dispersive optical bistability of a Fabry-Perot optical resonator due to the displacement of ultracold atoms trapped within. In the driven resonator, such collective motion is induced by optical forces acting upon up to

A Supramolecular Ferroelectric With Two Sublattices and Polarization Dependent Conductivity
Advanced Science, EarlyView.Ferroelectric behavior in a supramolecular material with two, independently switchable, sublattices is demonstrated. The sublattices can be associated with the two dipolar groups in the compound. Moreover, the polarization is found to couple to the charge transport in the material, giving rise to a switchable, directional conductivity.

Annular Vortex Chain in a Resonantly Pumped Polariton Superfluid
, 2014 We report the formation of a ring-shaped array of vortices after injection of angular momentum in a polariton superfluid. The angular momentum is injected by a $\ell= 8$ Laguerre-Gauss beam, whereas the global rotation of the fluid is hindered by a ...

Logic‐Gated HSV‐TK/GCV Suicide Gene Circuit for Triple‐Negative Breast Cancer
Advanced Science, EarlyView.The BRAS comprises two modular genetic components driven by distinct tumor‐specific promoters and a failsafe layer with the NOT gate. This multi‐input logic gate circuit enables precise, specific expression of HSV‐TK in breast cancer cells with hardly expression in normal cell and effectively inhibits tumor growth in a triple‐negative breast cancer ...

Dissipative solitons in pattern-forming nonlinear optical systems : cavity solitons and feedback solitons [PDF]
, 2005 Many dissipative optical systems support patterns. Dissipative solitons are generally found where a pattern coexists with a stable unpatterned state. We consider such phenomena in driven optical cavities containing a nonlinear medium (cavity solitons ...

Advanced Science, EarlyView.We demonstrate a hybrid WS2/CuInP2S6/graphene heterostructure integrated on a silicon nitride microring resonator for non‐volatile optical phase modulation with ultra‐low energy consumption and low insertion loss. While CIPS alone does not provide efficient optical index modulation, the engineered proposed device structure converts ferroelctric domain ...
