Optimization of Apodized Fiber Bragg Grating for Sensing Applications

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

Multi-parameter Sensing System Using Sampled Fiber Bragg Grating

We propose a Gaussian sampled fiber Bragg grating for multi-parameter sensing system. The sampled fiber Bragg grating combines the characteristics of fiber Bragg grating and long period grating. The transfer matrix method has been used to obtain the transmission spectrum of the grating. The shifts in narrowband loss peak and broadband loss peak in the transmission spectrum have been utilized to...

Unique 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...

Cascadability of Uniform Fibre Bragg Grating for 40 Gbit/s RZ-OOK to NRZ-OOK Conversion

The cascadability of uniform fibre Bragg grating for 40 Gbit/s return to zero on-off keying to non-return to zero on-off keying format conversion has been shown using OptSim simulation program. The main idea of this approach is use of specially designed uniform fibre Bragg grating with appropriate transfer function for shaping of 40 Gbit/s return to zero on-off keying optical spectrum.
