A low-cost technique using commercial UV grade silica fibers to construct microlens array that is suitable for mass-production of long-period gratings is reported. The growth rate of gratings fabricated using these arrays is much faster than the conventional amplitude masks. Our previous work had shown that this technique was 400% more efficient than the metal mask technique. Further improvement of this grating writing technique using plano-convex microlens array is reported in this paper. Under the same writing conditions, long-period gratings with absorption peaks of 1.5 dB and 17 dB were fabricated by using a microlens array and a plano-convex microlens array, respectively.
