Abstract

To increase its saturation threshold very strongly without degrading its gain, whilst remaining compatible with any semiconductor amplifier structure or technology, a semiconductor optical amplifier includes an input coupler having an input port and g output ports and an output coupler having g input ports and one output port. The q output ports of the input coupler are respectively connected to the q input ports of the output coupler by q semiconductor optical amplifiers having the same amplification characteristics. Applications include transmission of optical signals and to producing "all optical" switching devices.
