Abstract

A temperature-controlled, continuously and linearly tunable multiwavelength filter based on cascaded long period fiber gratings has been realized. For the first time, a tunable wavelength range of 2.1 nm has been achieved with a temperature variation of 62°C and a regression coefficient of 0.997. The experimental results are in good agreement with the theory.
