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...

| description | 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 wavelength range of 1397–1472 nm, enabled by 153-m of bismuth-doped fiber and two 7-m lengths of neodymium-doped fiber. The demonstration shows the possibility of achieving improved gain bandwidth by combining fiber amplifiers with overlapping gain spectra in the E-band. |
