Abstract:
1. A dispersion compensation module comprising: a polarization collimator; a polarization beam splitter coupled to the polarization collimator and having a first port, a second port, and a third port, the polarization beam splitter operable to receive a light beam at the first port, having a single polarization, from the polarization collimator, such that substantially the entire light beam is directed from the first port to the second port; a first reflection etalon optically coupled to the second port of the polarization beam splitter; and a second reflection etalon optically coupled to the third port of the polarization beam splitter, where the polarization beam splitter is positioned between the first reflection etalon and the second reflection etalon such that a light beam from the first reflection etalon passes, without deflection, through the polarization beam splitter to the second reflection etalon.
