ABSTRACT:
A semiconductor laser device capable of improving planarity of cleavage planes of an optical waveguide thereof is obtained. This semiconductor laser device includes a support substrate, a semiconductor laser element portion having a pair of cavity facets provided with ends of an optical waveguide extending in a first direction and a bonding layer bonding the support substrate and the semiconductor laser element portion to each other, while the bonding layer has void portions formed on regions close to at least the ends of the optical waveguide in the vicinity of the cavity facets.
