Abstract :
The chromatic dispersion of a single-mode fibre is successfully measured by means of an optical heterodyne detection method with temporal resolution of 0.01 ps. The heterodyne signal is detected at the near end of the fibre of length approximately 1 m using laser diodes operating in the 1.19¿1.51 ¿m wavelength region.
