Abstract:
1. An optical apparatus, comprising: a splitter that receives a time-division-multiplexed signal light multiplexed from a plurality of transmitting devices; a plurality of semiconductor amplifiers coupled to the splitter, each of the semiconductor amplifiers corresponding to each of a plurality of time slots along a time axis of the signal light; a multiplexer coupled to the plurality of semiconductor amplifiers, the multiplexer being configured to output a branched time-division-multiplexed signal light amplified by the plurality of semiconductor amplifiers that each correspondingly input each of the signal lights branched from the splitter; a receiver connected to the multiplexer; and a driving circuit connected to the plurality of semiconductor amplifiers, wherein the splitter is configured: the driving circuit configured: each of the plurality of semiconductor amplifiers configured: the multiplexer configured to generate a composite signal light by composing each amplified signal, and to input the composite signal to the receiver.
