Stable Spatial Solitons In Semiconductor Optical Amplifiers
The existence of stable dissipative spatial solitons at low intensities in patterened electrode semiconductor optical amplifiers (SOA) was investigated. A conventional SOA possessed unstable solitons because of the supercritical bifurcation of its plane-wave. It was shown that the stable bright spatial solitons existed in a periodically patterened electrode SOA where unpumped regions function as saturable absorbers.
