25 GHz polarization-insensitive electroabsorption modulators with traveling-wave electrodes

Electroabsorption modulators with traveling-wave electrodes have been designed and fabricated using MOCVD grown InGaAsP-InGaAsP quantum wells. A modulation bandwidth of 25 GHz is achieved for a 2 /spl mu/m-wide 30 /spl mu/m-long device. Driving voltage of 1.20 V is achieved for an extinction ratio of 20 dB for operation at 1.55 /spl mu/m.
