Vertical cavity lasers and their application to laser printing

We present the primary laser printing system performance issues which are the driving forces for multiple beam laser printing. Although edge emitting semiconductor lasers have allowed progress in this area, vertical cavity lasers have substantial advantage in the longer term. We further present needs and issues with VCSEL performance which must be addressed for the application of VCSELs to high performance laser printing. Finally, we explore advanced print architectures which would be enabled by the VCSEL device.
