摘要:
阵列波导光栅(AWG)是密集波分复用(DWDM)光网络中的关键器件,具有滤波特性好、性能稳定、串扰小的优点.介绍了AWG的结构和原理,在此基础上提出了用AWG实现光纤法布里珀罗(F P)传感器复用的方案.可调谐激光器和AWG的联合使用实现了时分复用和波分复用,系统的复用能力决定于可调谐光源的带宽、AWG的通道数和自由频谱范围.采用传统的强度法对传感器进行解调,解调结构简单,容易实现,传感器间无串扰.
Abstract:
Arrayed waveguide grating (AWG) is a key device in the DWDM op tical network and has the advantages of good filter capacity, steady performance and low crosstalk. The configuration and p rincip le ofAWG are described, and a scheme ofmultip lexing of fiber op tical FP sensors is p resented. The combination of tunable laser source ( TLS) and AWG makes time division multip lexing and wavelength division multip lexing possible. The number of sensors multip lexed in this system depends on the bandwidth of TLS, the number ofAWG channels and AWG free spectrum range ( FSR). Sensors are demodulated with the conventionalmethod of intensitywhich is of simp le configuration and easily carried out. There is little crosstalk between sensors.
