Abstract
The first measurements of dynamic spectra of an InGaAsP/InP electroabsorption light modulator under high-frequency large-signal modulation are reported. A spectral broadening factor ¿ was determined from the relative sideband strength to the carrier, and it decreased with increasing operating electric field in the modulator. The estimated ¿-value for full modulation was |¿| = 2.3, which can be reduced by designing a modulator to give a more effective change of electro-absorption.
