We show experimentally the existence of bright and dark spatial solitons in semiconductor resonators for excitation above the bandgap energy. These solitons can be switched on, both spontaneously and with address pulses, without the thermal delay found for solitons below the bandgap that is unfavorable for applications. The differences between soliton properties above and below gap energy are discussed.
