摘要
A method for forming a grating with an adjustable pitch and a method for forming a DFB-LD with an optical grating whose pitch is adjustable during the process are disclosed. The method of the invention; first prepares a mold with a pattern to form the grating; second, pushes the mold against the resin as deforming the mold; and third, hardens the mold. The resin with a periodic pattern whose pitch is adjustable during the process is available.
