Abstract
An optical fiber module has a package housing having an internal space defined by a base plate, a side wall, and a cover member, a laser device disposed on the base plate within the internal space, an optical fiber that transmits a laser beam emitted from the laser device to an outside of the package housing, a light scattering member that scatters light having a wavelength of the laser beam and covers an outer circumferential surface of the projecting end of the optical fiber, and a heat dissipation portion disposed on the base plate. The optical fiber has a projecting end projecting from an inner surface of the side wall toward the internal space. The heat dissipation portion covers a portion of an outer circumferential surface of the light scattering member and exposes another portion of the outer circumferential surface of the light scattering member to the internal space.
