    A new fiber position monitoring method for sequential FBG UV-writing processes with a reference phase mask as the phase reference is proposed. Also, the new method by probing a reference phase mask can overcome the optical alignment difficulties in using reference fiber as well as provide more signal power for achieving better monitoring accuracy. Moreover, the present invention provides a method for sequentially joining a plurality of grating sections into a fiber grating longer than a phase mask.

    Optimization correction of spectral distortion for superimposed DWDM multichannel fiber Bragg grating filters is performed with a hybrid Lagrange multiplier optimization algorithm to enable fast convergence as well as to retain the easy-fabrication merits.
