Optical frequency dissemination through hollow-core fibres

Popis výsledku v původním jazyce

The dissemination of phase-coherent signals through optical fibre links is typically influenced by induced phase noise. This is due to the Doppler effect and fibre length changes due to disturbing environmental influences (temperature changes, mechanical vibration, etc.). In the case of long-range fibre links, compensation methods based on fibre interferometers and appropriate action elements (acousto-optical modulator/frequency shifter, fibre stretcher) are usually involved in suppressing these unwanted signal distortions. In the case of short-range links, like interconnections between neighbouring laboratories or fibres between two different optical tables in the same room, these traditional methods are too sophisticated and complex. In this work, we describe the pilot experiment and the resulting performance of the optical frequency transfer through hollow-core photonic crystal fibre link, where the optical signal of 729 nm is disseminated by an air-filled hollow-core. We mainly focused on the link sensitivity to induced phase noise and its comparison to standard solid-core fibre link performance.
