Classification: CPC H  G | IPC G  H

Claim 0:
1. An optical amplification device comprising:
a first optical spatial layout converting unit configured to convert a spatial layout of a plurality of optical signal beams propagating through each of a plurality of cores, from a coupled state in which optical signal beams interfere between a plurality of cores to a non-coupled state in which optical signal beam interference is reduced between a plurality of cores;
an optical amplifying unit configured to amplify, in the non-coupled state, the plurality of optical signal beams with the non-coupled state and generate a plurality of amplified optical signal beams; and
a second optical spatial layout converting unit configured to convert a spatial layout of the plurality of amplified optical signal beams from the non-coupled state to the coupled state.
