Paper Abstract

A new method for fabricating Long Period Grating (LPG) using a microlens array is introduced. Instead of blocking the excimer laser beam, this new method convergences the UV laser beam into an intensity modulated profile and the writing efficiency is improved. This method enables shorter grating writing time and also suitable for batch production of LPGs, thus providing an efficient method with potential in the mass production of LPGs.
