Passive temperature compensated packages for short-period fiber gratings and other optical components and techniques for forming the packages are described. In one aspect, a hollow tube having a negative coefficient of thermal expansion (CTE) encased in a cylindrical body is employed to form an athermalized cylindrical package. The hollow tube may also include slots for writing a grating onto an optical fiber disposed within the tube. In another aspect, end caps may be disposed on opposite ends of the cylindrical body. |
