The fabrication and characterisation of two-dimensional photonic microstructures with a period of 190 nm exhibiting clear photonic bandgap effects is reported. We show that structures with near-perfect sixfold rotational symmetry are produced by elec

Double-quantum-well GaAs/AlGaAs ridge-waveguide lasers with integrated passive sections have been fabricated. Quantum wells in the passive-waveguide sections were intermixed with their barriers by dielectric-cap disordering, and a ridge waveguide was

We present what we believe is the highest efficiency and lowest threshold current density ever reported for semiconductor ring resonator lasers. Ring lasers are interesting components, e.g. for fiber-to-the-home systems, because they can readily be i

As the security environment of many states changes, some may be persuaded to explore defense strategies embodying methods of nonviolent civilian resistance. An important question for civilian-based defense strategies involves their deterrence potenti

This article examines the process of learning in the first two years of the Palestinian intifadah. During that period of the uprising, Palestinians deliberately employed a strategy of struggle that emphasized nonviolent action. Understanding how each

Building and sustaining cultures of peace does not mean eliminating conflict. Rather, conflict is to be expected. Sharp, even profound, disagreements among groups are almost inevitable in any social setting. These disagreements may be or become deepl

We report a novel technique for quantum well intermixing which is simple, reliable and low cost, and appears universally applicable to a wide range of material systems. The technique involves the deposition of a thin layer of sputtered SiO2 and a sub

We demonstrate that a quantum well intermixing technique can be used to control the second-order nonlinearity χzzz(2) in an AlGaAs asymmetric coupled quantum well waveguide structure at 1.52 μm. Photoluminescence measurements also indicate that the
