We report on the non-lithographic laser writing fabrication of polymer waveguide fanout on a newly developed 4′hydroxy-4-nitroazobenzene dye functionalized polymer film. It can avoid the time consuming costly error correction re-fabrication in conventional optical waveguide fabrication by lithographic techniques when encountering error due to imperfect fabrication. The laser writing correction of power splitting ratio on waveguide directional coupler and y-branch fanouts has been demonstrated.
