This paper deals with the designing of a Tm 3+ -doped chalcogenide Photonic Crystal Fiber (PCF) amplifier operating in the mid-IR range. The chalcogenide glass of 72GeS 2 –18Ga 2 S 3 –10CsI (in mol%) was fabricated with the high temperature melt-quenching method, which exhibited a strong emission peak around 3.8μm under the excitation of a 800nm laser. By employing...
