Abstract
The electroabsorption modulator with a high-mesa ridge waveguide has been fabricated on InP:Fe substrate to reduce the capacitance of electrode pads. The cut-off frequency was 40 GHz and the extinction ratio was 15 dB. The preliminary reliability test was carried out at dark state, and the estimated lifetime at 25°C was over 1.1×10 7 hours
