We present interferometric switching experiments using femtosecond pulses with an InGaAs semiconductor optical amplifier (SOA). Our measurements reveal significant refractive index changes occurring within a few picoseconds. The timescale and power dependence of this ultrafast feature, together with the predictions of a phenomenological model, strongly suggest carrier heating as responsible.
