Abstract

We report the first demonstration of a four-mode semiconductor optical amplifier (FM-SOA), with strategically positioned quantum-well layers to provide modal-gain control with uniform electrical pumping. On-off gain of 11 dB was demonstrated for all four modes (E11, E12, E21 and E22). The difference in on-off gain among all four modes is less than 1 dB in the range of 2-11 dB without any deliberately pumping profile control. Particular challenges with FM-SOA that must be overcome in comparison with traditional single mode SOA are discussed.
