Dual-fiber stretcher as a tunable dispersion compensator for an all-fiber optical coherence tomography system

摘要

We present an all-fiber tunable dispersion compensator based on a pair of fiber stretchers made with differ-nent fiber types in which the group delay and the second-order dispersion can be tuned independently. Itsnefficiency is demonstrated in a fiber-based optical coherence tomography (OCT) system operating in the 800nnm wavelength range. The average sample dispersion in OCT imaging or the dispersion of transmissionnlines could also be compensated by our system. © 2009 Optical Society of America
