SDL and Xerox propose to advance the state of the art in laser diodes by developing the technology to make monolithic arrays of laser diodes which can be individually activated, and which emit light at different, preselected frequencies over a broad range. The prototype device will be an array of four high-power lasers on 10 micron centers emitting infrared, red, green, and blue light. Applications for this kind of array would include color reprographics, color facsimile machines, compact color projection displays, high-density optical storage systems, high-resolution spectroscopes, and a variety of medical devices. Building a single semiconductor device with an array of lasers tuned to different frequencies will require important advances in semiconductor processing and device design, including: novel combinations of different semiconductors and insulators, fabrication of high-powered single-mode diode lasers for previously unreached wavelengths and at previously unreached power levels, and novel frequency-doubling systems. Intermediate technical advances are expected to have application to other optoelectronic devices. Stanford University will also work on the project as a subcontractor.
