This study deals with mechanically induced long period fiber gratings (MILPGs). First, an in-depth analysis of the most effective grating configuration of a grooved structure featuring a duty cycle of 40:60 using SMF- 28 is provided. Subsequently, a comparative analysis of MILPGs developed in various multi-layered optical fibers, including double cladding fibers with doped and pure-silica core as well as solid core photonic crystal fiber is presented. The demonstrated fabrication method highlights its adaptability for various types of fibers, eliminating the need for supplementary equipment or modifications, and operates independently of photosensitive fibers which marks the novelty of this work.
