Abstract :
An inverted slotline (ISL) was used to achieve velocity matching in a Ti-diffused LiNbO/sub 3/ waveguide optical modulator. Phase modulation of 1.38 radian could be observed at an optical wavelength of 0.63 mu m with 100-mW microwave power around 10 GHz. This ISL optical modulator is expected to operate at millimeter wavelengths.<>
