Abstract
A reflective doped fiber amplifier array utilizes an integrated circulator array to effect routing of optical signals. The integrated circulator array has a plurality of waveguide pairs coupled by polarization multiplexers formed in a planar substrate, and a nonreciprocal polarization rotation element positioned between sections of the waveguide pairs. Pump light is coupled into and out of the doped fibers by wavelength-selective reflectors.
