Optical bistability has been observed for the first time in a room-temperature InGaAsP/InP amplifier. Switching occurred at an optical input power of about 3 µW, corresponding to a change in the refractive index of 5 × 10[sup -4]. The results are discussed in terms of a light-induced change in carrier concentration. Implications for bistability in passive devices are also discussed.
