Abstract
A hermetic seal device for a polarization-maintaining optical fiber is provided. The hermetic seal device includes a polarization-maintaining optical fiber and a cylindrical member to be inserted by the polarization-maintaining optical fiber, where the cylindrical member has the difference 3×10−6/K or less in expansion-coefficient absolute value between the polarization-maintaining optical fiber and the cylindrical member.
