ABSTRACT:
A multichannel integrated optics modulator is disclosed that generates one or more independently modulated scanning beams. The integrated optics modulator includes at least one waveguide channel provided on an electro-optic substrate, wherein the waveguide channel is divided into a write waveguide channel that extends to an output side of the substrate and a dead-end waveguide channel that terminates before reaching the output side of the substrate. Control signals are selectively applied to electrodes provided above the dead-end waveguide channel and the write waveguide channel to control the coupling of light from the write waveguide channel to the dead-end waveguide channel. Light is coupled out of the dead-end waveguide channel through the use of an absorber located above an end region of the dead-end channel. The integrated optics modulator is incorporated in a variety of scanner mechanisms.
