Abstract
A laser device () includes: a branch waveguide () configured to split light propagating from an optical amplifier () into a plurality of light beams and output the plurality of light beams; a multi-core waveguide () including a plurality of waveguide cores (to) configured to carry the plurality of light beams input from the branch waveguide (); and a light reflector () optically coupled to a light input/output end of the multi-core waveguide (). The waveguide cores (to) are configured to extend along the same direction, and placed in proximity to one another to enable optical coupling between adjacent waveguide cores of the waveguide cores (to).
