✦ Synopsis

A new technique for generating a continuous range of true time delay values is introduced. Heating optical ÿber in order to change the e ective index of the guided mode produces time delays. A 45-m section of single-mode silica ÿber is demonstrated to produce a continuous range of time delay values from 0 to 211 ps over a temperature tuning range of 50 • C (30-80 • C). A thermal time delay factor is introduced and found to be 0:096 ps=m • C for Corning LEAF ÿber. A 7.66-m section of multimode Lucina polymer ÿber is demonstrated to produce a range of time delay values from 0 to 32 ps over a temperature tuning range of 30 • C (30-60 • C). The thermal time delay factor for this ÿber is -0:1427 ps=m • C.
