Optical amplifiers and lasers using erbium-doped optical fibers
Original language description
We report properties on erbium-doped fiber for amplifier and fiber laser applications. Key factors such as pump source, power, and fiber length were analyzed to optimize system performance. Results show that erbium-doped fiber amplifiers (EDFAs) achieve high gain under specific conditions: 980 nm pumps perform better at high power, while 1480 nm pumps yield higher gain at low power. Gain efficiency is strongly dependent on the 1550 nm signal power, decreasing at higher levels (~20 μW) due to gain saturation. The optimal setup—980 nm forward pumping at 160 mW with a 1550 nm signal at 5 μW—achieved a maximum gain of 18.76 dB using 6 m of erbium-doped fiber. In fiber laser experiments, erbium-doped fiber was integrated into Bragg grating and ring resonator designs. The Bragg grating at 1550 nm gave the highest output power of 1.171 mW, while the grating at 1545 nm had the best full width at half maximum (FWHM) value of 80 pm under a 980 nm pump power of 170 mW. On the other hand, the ring laser was at its best performance when it used a 3 meters erbium-doped fiber and a pump power of 170 mW at 980 nm with a maximum output power of 441.2 μW.
