Thermally tunable optical dispersion compensation (ODC) devices are
disclosed. In one aspect, an ODC device may include multiple
Gires-Tournois (G-T) etalons. The etalons may be optically coupled
together. The etalons may compensate for optical dispersion by
collectively delaying light. At least one of the G-T etalons may have a
temperature dependent partial reflector. The ODC device may also include
at least one thermal device to change the temperature of the G-T etalon
having the temperature dependent partial reflector. Methods of making and
using the ODC devices are also disclosed, as well as various systems
including the ODC devices.
