Short-haul fibre-optic communication link with a phase noise compensation system for optical frequency signal transmission

摘要

A 5-m-long fibre link with a phase noise compensation system for optical frequency signal transmission at a wavelength of 1.14 mu m is demonstrated. The stability of the noise compensation system in the presence of harmonic mechanical perturbations is assessed and the relative transmitted signal frequency instability is shown to be 3.8 x 10(-15) at an averaging time of 1 s and 3.5 x 10(-20) over 850 s.
