Achieving Directional Oil Manipulation by Open Inducing Structure for Electrowetting Displays

open access: yesAdvanced Electronic Materials, EarlyView.
This work introduces an open inducing structure (OIS) fabricated by photoembossing to precisely control oil motion in electrowetting displays (EWDs). The OIS creates local electric field inhomogeneity, guiding directional oil rupture and achieving a 93.8% motion consistency. It significantly lowers the turn‐on voltage and accelerates the response speed,

Dissipative solitons in pattern-forming nonlinear optical systems : cavity solitons and feedback solitons [PDF]

open access: yes, 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 ...

Polarization bistability and resultant spin rings in semiconductor microcavities

open access: yes, 2010
The transmission of a pump laser resonant with the lower polariton branch of a semiconductor microcavity is shown to be highly dependent on the degree of circular polarization of the pump.

High temperature, experimental thermal memory based on optical resonances in photonic crystal slabs

open access: yesAPL Photonics, 2019
We present an experimental thermal memory with direct optical control and readout. Information is stored in the internal temperature of the device, while laser illumination is used to read, write, and erase stored bits.

Material‐Based Intelligence: Autonomous Adaptation and Embodied Computation in Physical Substrates

open access: yesAdvanced Intelligent Systems, EarlyView.
This perspective formulates a unifying framework for Material‐Based Intelligence (MBI), defining the physical requirements for materials to achieve embodied action, active memory and embodied information processing through intrinsic nonequilibrium dynamics. The design of intelligent materials often draws parallels with the complex adaptive behaviors of
