Abstract:
(EN) An optical fiber laser, comprising a pumping light source (140), a resonant optical circuit (110), a tuning device (120) and a current adjustment device; the pumping light source provides pumping light for the resonant optical circuit; the tuning device is provided on the resonant optical circuit, and the tuning device comprises a grapheme film (121) and a first optical fiber (122), the grapheme film covering the end face of a fiber core on one end of the first optical fiber; and the current adjustment device is connected to the grapheme film, and the current adjustment device is used for energizing the grapheme film and adjusting the current passing through the grapheme film. On one hand, as the current passing through the grapheme film is adjustable, the temperature of the grapheme film is adjustable, and the depth of modulation performed by the tuning device on the laser transmitted therethrough is changed, making the performance of the optical fiber laser tunable. On the other hand, the tuning device is an optical fiber device integrating the first optical fiber and the grapheme film, and therefore, the loss of an optical signal during transmission of same through the tuning device is small, enabling the optical fiber laser to have a better tuning effect.
(FR) Un laser à fibre optique, comprenant une source de lumière de pompage (140), un circuit optique résonant (110), un dispositif d'accord (120) et un dispositif de réglage de courant ; la source de lumière de pompage fournit une lumière de pompage pour le circuit optique résonant ; le dispositif de syntonisation est disposé sur le circuit optique résonant, et le dispositif de syntonisation comprend un film de graphène (121) et une première fibre optique (122), le film de graphène couvrant la face d'extrémité d'un cœur de fibre sur une extrémité de la première fibre optique ; et le dispositif de réglage de courant est connecté au film de graphène, et le dispositif de réglage de courant est utilisé pour exciter le film de graphène et régler le courant traversant le film de graphène. D'une part, étant donnée que le courant traversant le film de graphène est réglable, la température du film de graphène est réglable, et la profondeur de modulation effectuée par le dispositif d'accord sur le laser transmis à travers celui-ci est modifiée, rendant les performances du laser à fibre optique accordable. D'autre part, le dispositif d'accord est un dispositif à fibre optique intégrant la première fibre optique et le film de graphène, et par conséquent, la perte d'un signal optique pendant la transmission de celui-ci à travers le dispositif d'accord est faible, permettant au laser à fibre optique de posséder un meilleur effet d'accord.
(ZH) 一种光纤激光器包括泵浦光源(140)、谐振光路(110)、调谐器件(120)和电流调节器件;泵浦光源为谐振光路提供泵浦光;调谐器件设置在谐振光路上,调谐器件包括石墨烯膜(121)和第一光纤(122),石墨烯膜覆盖第一光纤一端的纤芯的端面;电流调节器件与石墨烯膜连接,电流调节器件用于使石墨烯膜通电,并调节通过石墨烯膜的电流。一方面,通过石墨烯膜的电流可调节,石墨烯膜的温度可调节,调谐器件对于穿过其传输的激光的调制深度改变,使得光纤激光器的性能可调谐。另一方面,调谐器件是第一光纤与石墨烯膜集成的光纤器件,因此,光信号通过调谐器件传输时的损耗较小,使光纤激光器的调谐效果好。
