Optical bistability in a Fabry-Perot semiconductor laser amplifier is discussed when two optical inputs detuned from the resonant wavelength of a semiconductor laser amplifier are injected. A new split branch is found in the optical output versus input characteristics in addition to conventional optical bistable behavior. It is also shown analytically and experimentally that set and reset can be achieved in the optical output of the semiconductor laser amplifier for each wavelength by applying two detuned optical pulses and using the split branch.
