A highly versatile electro-optically induced waveguide is proposed, and some of its applications are discussed. The In<sub>1−<i>s</i></sub>Ga<sub><i>s</i></sub>As<sub><i>t</i></sub>P<sub>1−<i>t</i></sub>-based device can reconfigure an arbitrary refractive-index profile with high speed by using an array of stripe electrodes deposited along the device. This device can act as a variable fractional Fourier transformer or as a beam shaper. Some nonguiding applications based on a specific refractive-index patterning that is normal to the light-propagation direction, such as phase modulation and beam steering, can also be implemented with this device.
