摘要

The overall procedure toward the implementation of a compact tunable athermal filter mounted on a piezoelectric actuator and based on a 7r-shift chirped fiber Bragg grating is presented. This package ensures an active tunablility over 2 nm with a cross thermal induced Bragg wavelength shift below 100 pm over a temperature range from - 20℃ to + 80℃. The proposed filter makes use of the overall response of a π-shift chirped fiber Bragg grating and a bulk broadband microf ilter that enables a sharp optical transmission spectrum response having a FWHM below 20 pm within a 2 nm region and 20 dB rejection band to be obtained.
