摘要: 对光纤光栅的调谐特性进行了理论分析和实验研究, 并利用压电陶瓷作为调谐物质实现了调谐范围达1.344 nm的电调谐光纤光栅器件.与其它类型的可调谐光纤光栅相比, 该器件具有结构简单、 易于实现, 且机械稳定性强的优点.此外, 还对光纤光栅弯曲所导致的其Bragg波长的迁移特性进行了实验研究, 获得了1.68 nm的波长调谐范围.

Abstract: The tuning characteristics of the fiber Bragg gratings are analyzed on theory and experiment, and a tunable fiber Bragg grating device with a PZT has been realized, which can be tuned about 1.344 nm. Compared with other types of tunable fiber Bragg grating, this device has the advantages ofsimple structure, easy realization and stable performance. By the way, the tuning characteristics of the fiber Bragg grating are also studied when bending it inexperiment, and the tuning range is about 1.68 nm.

Key words: wavelength division multiplexing, fiber gratings, wavelength selection and tuning
