摘要：

The first measurements of selfphase modulation and nonlinear absorption in a GaAs/GaAlAs multiquantum well (MQW) waveguide near the half-bandgap resonance are reported. An intensity-dependent refractive index coefficient n2 of 9 x 10(-14) cm2/W and a two-photon absorption coefficient of 0.15 cm/GW at 1.55-mu-m wavelength for TM light were obtained. This corresponds to an intensity-independent figure of merit of 24rad phase change in one nonlinear absorption length, high enough to allow the implementation of subpicosecond all-optical switches at 1.55-mu-m wavelength.
