Abstract

Several organizations are engaged in the development of deployable optical communication systems for intersatellite and satellite to ground communications supporting commercial and non-commercial objectives. The debate whether to use 1.0 or 1.5 μm continues, although the prevailing view leans toward the latter because of its connection with commercial telecom. Solutions at 1.0 μm, however, enable greater efficiency, which is more appealing for small SWaP constrained systems. To promote an increased interoperability potential, we have explored amplification at both wavelengths using an ErYb-only fiber amplifier and a hybrid Yb/ErYb segmented fiber amplifier configuration. These configurations allow the user to select either wavelength without implementing two independent amplification systems. The work presented here will discuss the difficulties encountered with the former approach, modeling efforts, and recent results with the segmented solution.
