Abstract
We demonstrate a largely tunable dispersion fiber Bragg grating (FBG) inscribed in microstructured polymer optical fiber (mPOF). The bandwidth of the chirped FBG (CFBG) was achieved from 0.11 to 4.86 nm, which corresponds to a tunable dispersion range from 513.6 to 11.15 ps/nm. Furthermore, thermal sensitivity is used to compensate the wavelength shift due to the applied strain. These results demonstrate that CFBG in POF is a promising technology for future optical systems.
