摘要：

Modulated light spectra are measured in long-wavelength InGaAs-InAIAs multiple-quantum-well intensity modulators under 30 GHz large signal modulation. The linewidth broadening factor alpha is determined from the relation between the intensity modulation index and the side-band strength relative to the carrier. The minimum alpha value is estimated to be 0.70, which is almost the same as the lowest value so far reported in a bulk Franz-Keldysh modulator.
