Abstract
An optical amplification system includes: an optical mixer which combined first light, second light, third light, and fourth light, then branches the combined lights, and outputs first combined light, second combined light, third combined light, and fourth combined light; a first brancher that branches the first combined light and outputs first excitation light and second excitation light; a second brancher that branches the second combined light and outputs third excitation light and fourth excitation light; a third brancher that branches the third combined light and outputs fifth excitation light and sixth excitation light; and a fourth brancher that branches the fourth combined light and outputs seventh excitation light and eighth excitation light.
Claims3
An optical amplification system comprising:
- a first optical source that outputs first light;
- a second optical source that outputs second light;
- a third optical source that outputs third light;
- a fourth optical source that outputs fourth light;
- an optical mixer that multiplexes the first light, the second light, the third light, and the fourth light, then splits the multiplexed light, and outputs first multiplexed light, second multiplexed light, third multiplexed light, and fourth multiplexed light;
- a first brancher that splits the first multiplexed light and outputs first excitation light and second excitation light;
- a second brancher that splits the second multiplexed light and outputs third excitation light and fourth excitation light;
- a third brancher that splits the third multiplexed light and outputting outputs fifth excitation light and sixth excitation light;
- a fourth brancher that splits the fourth multiplexed light and outputs seventh excitation light and eighth excitation light;
- a first amplifier that amplifies a first optical signal by using the first excitation light and amplifies a second optical signal by using the second excitation light;
- a second amplifier that amplifies a third optical signal by using the third excitation light and amplifies a fourth optical signal by using the fourth excitation light;
- a third amplifier that amplifies a fifth optical signal by using the fifth excitation light and amplifies a sixth optical signal by using the sixth excitation light;
- and
- a fourth amplifier that amplifies a seventh optical signal by using the seventh excitation light and amplifies an eighth optical signal by using the eighth excitation light.
