Abstract :
1.31-μm electroabsorption modulators monolithically integrated with a DFB laser diode have been realized using an identical InGaAsP-InP multiple quantum-well-layer structure composed of two different QW types. Low laser threshold currents <13 mA and high 3-dBe cutoff frequency up to /spl sim/25 GHz have been measured.
