Pixellation of optically bistable elements

Optical and Quantum Electronics, 1989
The elements of optical logic arrays can, in principle, be shielded from inter-element crosstalk by material pixellation. This confinement might seem to allow closer packing of such elements. However, using a Fourier optics approach to diffusion, we show that the pixellation process itself prevents radial removal of heat, and this can seriously affect ...

Stretch Tunable Active Frequency Selective Fabric for Dynamically Switchable Bandstop and Transparency

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
This stretchable active frequency selective fabric achieves reversible switching between bandstop and transparent states through strain‐induced reconfiguration of its conductive network. Its zero‐power and mechanically tunable characteristics offer potential for wearable electromagnetic functional materials.

Measurement and application of optical nonlinearities in indium phosphide, cadmium mercury telluride and photonic crystal fibres

, 2009
The two-photon absorption (TPA) coefficient is measured in indium phosphide (InP) using femtosecond pulses to be 45cm/GW at 1.32μm. Nanosecond pulses are subsequently used to find the free-carrier refractive index cross-section, σ_r, and the free-carrier

Optical-force-induced bistability in nanomachined ring resonator systems

, 2012
This paper reports optical-force-induced bistability in a nanomachined ring resonator system. It consists of two ring resonators and a bus waveguide, whereby each ring resonator has a free-hanging arc that is perpendicularly deformable by an optical ...

Hydroquinone Oxidation by Redox‐active Guanidines and Thioguanidines: Faster Conversion to High‐Potential Than to Low‐Potential Quinones

Chemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.
New redox‐active oligothioguanidines are developed and used in dehydrogenative P–P coupling reactions and hydroquinone oxidations. Tetrathioguanidino‐ and tetraguanidinobenzenes oxidize high‐potential halogenated hydroquinones faster than relatively low‐potential hydroquinone.

Redox‐Active Guanidines

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...
