چکیده
This paper presents the modeling and characterization of an Apodized optical fiber Bragg grating for maximum reflectivity and minimum side lobe power wastage and narrow spectral response. The modeling is based upon coupled mode theory together with transfer matrix method. This matrix approach is effective at treating a single grating as a series of separate

متن کاملHybrid Raman/fiber Bragg grating sensor for distributed temperature and discrete dynamic strain measurements.
We propose and experimentally demonstrate a hybrid fiber optic sensing technique that effectively combines Raman optical time domain reflectometry and in-line time-division-multiplexing for fiber Bragg grating (FBG) dynamic interrogation. The highly integrated proposed scheme employs broadband apodized low reflectivity FBGs with a single narrowband optical source and a shared receiver block, al...
متن کاملFiber Bragg Gratings for Dispersion Compensation in Transmission: Theoretical Model and Design Criteria for Nearly Ideal Pulse Recompression
We propose a transmission-based dispersion compensator employing an apodized, unchirped fiber Bragg grating (FBG). A theoretical model for dispersion compensation in transmission based on the dispersive properties of the periodic structure is developed. A figure of merit is defined for optimization of the grating parameters for maximum recompression of dispersion-broadened optical pulses in lon...
متن کاملUnique Solution of Short Pulse Propagation in Nonlinear Fiber Bragg Grating
In this study, a new numerical method is introduced to obtain the exact shape of output pulse in the chalcogenide fiber Bragg grating (FBG). A Gaussian pulse shape with 173 ps width is used as an input pulse for lunching to a 6.6 mm nonlinear FBG. Because of bistable and hysteresis nature of nonlinear FBG the time sequence of each portion of pulse is affected the shape of output pulse. So we di...
