Abstract :
We demonstrate the first integration of active electronic devices with semiconductor waveguide modulators. By combining ion-implanted GaAs MESFET amplifiers with directional-coupler electro-optic modulators, the DC drive voltage has been reduced by a factor of ¿v = 9, making an effective electro-optic figure-of-merit ¿vn3r41 for GaAs superior to that of LiNbO3
