Abstract

We report the design and performance of Holmium-doped fiber amplifiers (HDFAs) with novel alternative in-band pump wavelengths in the 1720—2000 nm spectral region. We demonstrate through simulations that pump wavelengths of 1840—1860 nm can yield significantly improved output power (3—6 dB), gain (8—10 dB) , and optical-optical conversion efficiency compared to the previous technical and industry standard pump wavelength of 1940 nm. Experimental results fully confirm our simulations.
