The oscillation frequency is proportional to the reciprocal of the propagation delay which depends on temperature by the way of the effective refractive index of the fiber. In case of a long fiber loop, even a small change of the temperature can induce an oscillation frequency drift. In this paper, a system based on a vector network analyzer (VNA) is proposed to monitor the oscillation frequency drift with a minimum of extra optical components. There is a good correlation between the phase evolution determined by the VNA and the OEO frequency drift. Knowing the drift it is possible to correct results obtained from the OEO used as an optical path measurement tool for either distance or refractive index variation detection. date: 2014-10-01 date_type: published official_url: Doi: 10.1109/ATC.2014.7043422 full_text_status: none pres_type: paper pagerange: 411-416 event_title: 2014: The 7th International Conference on Advanced Technologies for Communications (ATC 2014) event_location: Hanoi, Vietnam event_dates: 15-17 October 2014 event_type: conference refereed: TRUE citation: Pham, Toan Thang and Bach, Gia-Duong and Vu, Van Yem and Ledoux-Rak, I and Journet, Bernard (2014) Monitoring the Oscillation Frequency Drift of an Optoelectronic Oscillator with a Vector Network Analyzer.
