SPATIAL SOLITON PIXELS IN SEMICONDUCTOR-DEVICES

Semiconductor devices are the most appealing systems for information e ncoding using two-dimensional spatial solitons, recently reported both theoretically and experimentally in model systems. We show that stabl e solitons can be realized and controlled, both in passive microresona tors with excitonic nonlinearity and in below-threshold vertical-cavit y lasers. The solitons are robust enough to withstand significant carr ier diffusion and self-defocusing, which is very encouraging for devic e applications.
