The letter reports the first demonstration of thermally stable, optical bistability in a passive InGaAs/InGaAlAs multiquantum well nonlinear Fabry-Perot etalon at the wavelength 1.5 µm. Critical switch powers of 1 mW were obtained, permitting operation with a CW diode laser source. Switch on/off times of 14 ns/40 ns were observed under slow ramping conditions.
