High gain and wideband hybrid optical amplifier using bismuth-doped and neodymium-doped fibers for E-band applications
Abstract A hybrid dual-stage bismuth-doped fiber and neodymium-doped fiber amplifier with high optical gain and extended bandwidth of operation in the E-band is demonstrated. The amplifier features a maximum gain of 43 dB, output power of 372 mW, and a minimum noise figure of 5.5 dB, and operation w...
