Abstract: A photonic integrated circuit, comprising a semiconductor photonic substrate having integrated therein: at least one light receiving input; at least one optical splitter to branch light received at the at least one light receiving input to a first light path and a second light path; wherein, the photonic integrated circuit, in the first light path, includes: at least one first amplifier structure to amplify the light in the first light path to provide first amplified light; at least one first light output to output the first amplified light from the at least one first amplifier structure; and at least one first photo detector to receive light from the outside of the photonic integrated circuit, the at least one first photo detector being located next to the at least one first light output; wherein, the photonic integrated circuit, in the second light path, includes: at least one second amplifier structure to amplify the light in the second light path to provide second amplified light; at least one second light output to output the second amplified light from the at least one second amplifier structure; and at least one second photo detector to receive light from the outside of the photonic integrated circuit, the at least one second photo detector being located next to the at least one second light output.
