Paper Abstract

A novel bidirectional center wavelength tuning method of Fiber Bragg Grating (FBG) was put forward in this paper. It is based on bidirectional temperature control unit, including semiconductor cooler/heater, negative temperature coefficient (NTC) resistor and peripheral circuits. The cooler/heater, NTC and a FBG were integrated in a DIL metal package like common laserdiodes. Wavelength tuning experiments were carried out at three different environment temperature (0°C, 20°C and 40°C), and the temperature tuning range is from -20°C to 60°C with a step of 10°C. The experimental results show that center wavelength of FBG changes linearly along with temperature variation, and the linearity is better than 0.9986, moreover, environment temperature has little influence on FBG's center wavelength.
