Kk. Koi et al., HIGH SATURATION POWER 1.3-MU-M MQW ELECTROABSORPTION WAVE-GUIDE MODULATORS ON GAAS SUBSTRATES, IEEE microwave and guided wave letters, 7(10), 1997, pp. 320-322
An analog InGaAs/InAlAs multiple-quantum-well electroabsorption wavegu
ide modulator operating at 1.32-mu m wavelength has been designed, fab
ricated, and characterized for the first time on a GaAs substrate, A t
ypical 3-mu m-wide 115-mu m-long device exhibits a high optical satura
tion power in excess of 17 mW and a 3-dB electrical bandwidth of 20 GH
z. An equivalent half-cave voltage V-pi of 2.8 V has also been achieve
