Conventional optical waveguide fabrication by lithographic techniques can result in waveguide devices that cannot be repaired or corrected after the fabrication process. Especially when encountering error due to imperfect fabrication, a time consuming costly error correction re-fabrication would be required. We report on the non-lithographic laser writing fabrication of polymer waveguide on a newly developed 4'-hydroxy-4-nitroazobenzene dye functionalized polymer film that can avoid the error correction re-fabrication. The laser writing correction of power splitting ratio on waveguide directional coupler and y -branch fanouts has been demonstrated.
