Phys. Rev. Lett. 79, 2042–2045 (1997)Spatial Soliton Pixels in Semiconductor DevicesReceived 22 April 1997; published in the issue dated 15 September 1997 Semiconductor devices are the most appealing systems for information encoding using two-dimensional spatial solitons, recently reported both theoretically and experimentally in model systems. We show that stable solitons can be realized and controlled, both in passive microresonators with excitonic nonlinearity and in below-threshold vertical-cavity lasers. The solitons are robust enough to withstand significant carrier diffusion and self-defocusing, which is very encouraging for device applications. © 1997 The American Physical Society URL:
