An athermalized delay line having two optical paths whose difference in optical path length is thermally insensitive. Each optical path typically includes a reflecting quarterwave plate, each path being fed by the output from a polarizing beamsplitter. The delay line is suitable for incorporation into a PMD compensator having at least one compensation stage formed from a polarization controller and an athermalized delay line.
