Study on the Characteristics of Long Period Grating in Polarization Maintaining Fiber
In this paper, the characteristics of long-period Bragg grating written on panda fiber are presented. Both the strain and temperature responses show a good linear characteristics at the strain range and temperature range investigated. The temperature-tuning characteristics of the long period grating (LPG) by using a thin film metal coating on the nude surface of the fiber as a heater are also demonstrated. In the range of 0~150 mA, the response curve of the LPG has good linearity with the square of the current, while the loss change is less than 0.3 dB.
