Abstract :
Low-voltage driving and high-speed modulations of InGaAsP/InP electroabsorption modulators with strip-loaded planar waveguide have been described. The modulators were fabricated from VPE-grown InGaAsP/InP double-heterostructure wafers. For ¿=1.55 ¿m incident light an extinction ratio of 20 dB was achieved with an applied voltage of ~¿6 V. The insertion loss was 9.6 dB. The calibrated 3 dB bandwidth was 1.6 GHz.
