An optical fiber wavelength reference device (110) for tuning a tunable Fabry- Perot filter (105) and/or a tunable VCSEL (105) to a desired frequency, where the device uses a fiber etalon (120) to generate a pattern of reference frequencies against which the device is tuned. In addition, the device uses a detector (125) to monitor the output of the Fiber Etalon (120). The ouput of the detector (125) is inputed to a controller (115) used to control the VCSEL (105) or tunable Fabrey-Perot filter (105).

L'invention concerne un dispositif de référence de longueur d'onde de fibres optiques permettant de régler un filtre Fabry-Pérot réglable et/ou un laser à cavité verticale (VCSEL) réglable sur une fréquence désirée. Ce dispositif utilise un étalon de Fabry-Pérot afin de générer une référence type de fréquences sur laquelle se règle le dispositif.
