Patent ID: 7623560

Claim:
An emissive multicolor digital image forming (imager) device comprising; a two dimensional array of multicolor laser emitting pixels whereby each multicolor laser emitting pixel comprises: a plurality of laser diode semiconductor structures, each for emitting a different color, stacked vertically with a grid of vertical sidewalls electrically and optically separating each multicolor pixel from adjacent multicolor pixels within the array of multicolor pixels; and a plurality of vertical waveguides optically coupled to the laser diode semiconductor structures to vertically emit laser light generated by the laser diode semiconductor structures from a first surface of the stack of laser diode semiconductor structures; the stack of laser diode semiconductor structures being stacked onto a digital semiconductor structure by a second surface opposite the first surface of the stack of laser diode semiconductor structures; and a plurality of digital semiconductor circuits in the digital semiconductor structure, each electrically coupled to receive control signals from the periphery of the digital semiconductor structure and electrically coupled to the multicolor laser diode semiconductor structures by vertical interconnects embedded within the vertical sidewalls to separately control the on/off states of each of the multicolor laser diode semiconductor structures.
