Paper Abstract

Optical waveguides are considered and investigated for laser beam combining and colour homogenization for use in a three colour laser based display system. A recently developed laser is calibrated and the best method for designing an all-waveguide combining and homogenising system is investigated. Ray tracing simulations are performed and the results are presented. An optical combination of lenses is designed and used for laser beam focusing into a 200 μm fibre core diameter step index silica core multimode fibre. We also designed and simulated a slab waveguide for beam shaping and beam homogenizing.
