Abstract:  Qualcomm continues to lead the development of mobile communications technology.  A key component for this technology is the display.  Qualcomm has developed a pixelated metallic membrane based display called Mirasol.  This reflective display required the development of thin, planar format front light technology.  In turn, this research effort has spawned a series of planar optical based devices such as a flat lens less camera, a unique optical touch screen and a near field three dimensional user interface.  This presentation describes the optics of these devices.

Bio:  Russ began his optics career by completing the Ph.D. in optics at the University of Rochester.  His doctoral studies in plasmonic physics gave him optical microstructure fabrication experience. His first jobs in industry concentrated on the design and fabrication of optical micro structured surfaces for applications in aerospace technology and diffractive optics for CO2 industrial lasers.  A turning point in his career occurred when he learned non-sequential optical ray-tracing.  This skill opened the doors for successive positions in optical systems simulation and design.  These positions have culminated with developing the design infrastructure for and then leading a team in front light development.  Currently, he leading a team in the development of planar optical based devices in Qualcomm’s corporate research labs.
