Abstract

An optical frequency distribution system has been developed that continuously delivers a stable optical frequency of 268 THz (corresponding to a wavelength of 1118 nm) to different experiments in our institute. For that purpose, a continuous wave (cw) fiber laser has been stabilized onto a frequency comb and distributed across the building by the use of a fiber network. While the light propagates through the fiber, acoustic and thermal effects counteract against the stability and accuracy of the system. However, by employing proper stabilization methods a stability of 2 x 10−13 τ-1/2 is achieved, limited by the available radio frequency (RF) reference. Furthermore, the issue of counter-dependant results of the Allan deviation was examined during the data evaluation.

Distributing the frequency comb (left) or single stabilized cw signals (right). The two grey boxes indicate that these steps are optional - depending on the application after the distribution. As it turns out in subsection 3.3, a Doppler correction is only required if the application’s accuracy has to be better than 10−14.
