A novel concept for an all-optical flip-flop composed of a single distributed feedback (DFB) laser is proposed. A bistability in the laser power can be observed when light of a different wavelength is injected in the DFB laser. This can be explained by the drastical change of the carrier distribution in the laser due to spatial hole burning effects. It is possible to exploit this bistability for fast flip-flop operation by injecting pulses at both sides of the laser.
