This paper presents a systematic review of long period fiber gratings (LPFGs) written by theCO2laser irradiation technique. First, various fabrication techniques based onCO2laser irradiations are demonstrated to write LPFGs in different types of optical fibers such as conventional glass fibers, solid...
