Title:
LIGHT SOURCE DEVICE AND OPTICAL AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2020/004224
Kind Code:
A1
Abstract:
Provided are a light source device that is suitable for an optical amplifier including a plurality of optical amplification units and that can emit excitation light of optimal intensity to each of the optical amplification units, and an optical amplifier that uses this light source device. The light source device includes: first and second light sources that each emit excitation light; and a polarization beam combiner that includes first and second input ports and first and second output ports and that multiplexes/demultiplexes the excitation light emitted from the first and second light sources and inputted to the first and second input ports.
