Abstract
The characteristics of long period fiber grating transmission in uniform temperature field and non-uniform temperature fields is theoretically analyzed.The spectrum characteristics of long period fiber grating transmission in uniform temperature field and non-uniform temperature field with experiments are demonstrated.Experiments prove that with the rise of temperature,the synchronous wave center of fiber grating drifts to the long wave direction,the reverse is also the true,and drift distance has linear relations with the variation of temperature.In non-uniform temperature filed,when the temperature difference on both grating ends of long period fiber grating changes,the 3dB spread of synchronous waves show the linear increasing trend.

期刊介绍:
The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months.
The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
