摘要
In this paper we report the study of a single mode fiber grin lens tunable Fabry-Perot filter. The Fabry-Perot filter consists of two grin lens on which the multi-layer film with high reflectivity is deposited. The cavity is tuned continuously over the whole wavelength range of 40nm by a piezoelectric transducer (PZT). The device has a free spectrum of 30nm and 3dB peak bandwidth is less than 1dB. The filter can be applied to wavelength interrogation in fiber Bragg grating (FBG) sensing system to detect the drift of the Fiber Bragg wavelength.
