An optical module equipped with at least one optical component, a package for housing the one optical component, and a joining portion. The joining portion is formed within the package by Sn&#x2014;Ag solder containing 2.0 to 5.0 wt % Ag and 2.0 to 20.0 wt % Au, or Sn&#x2014;Zn solder containing 6.0 to 10.0 wt % Zn and 2.0 to 20.0 wt % Au.

Optical module and method of assembling the optical module

A lensed polarization maintaining fiber having a lens on an end thereof has a core, two stress-applied regions disposed on both sides of the core, respectively, and a clad containing the core and stress-applied regions. The lens has at least an inclined face, the inclined face including an edge. Each of the stress-applied regions is exposed on the inclined face except the edge.
