  The threshold pump power for modelocking decreased by 18% when the
temperature was increased from 25 to 100 degrees C, where a SWCNT/PDMS coated
tapered fiber was used as the saturable absorber in a fiber laser. Further, the
pump power at which multi-pulse operation began decreased by 24%, and the pump
power range over which fundamental modelocking could be maintained decreased by
59% over the same temperature range. This decrease in stability is attributed
to the large thermo-optic coefficient of the PDMS polymer, which results in a
40% reduction of the overlap between the evanescent field and SWCNT coating of
the taper fiber over a temperature range of 75 degrees C.
