Uniform Apodized Fiber Bragg Grating
An AUFBG is connected between the MZM and the SSMF at the transmitter and another one between EDFA and PIN photodetector at the receiver. Table 5 illustrates the obtained results of this case for all apodization functions. It is noticed tanh profile in case three (post-compensation scheme) achieves the best Q-factor (9.

Fiber Bragg Grating Mode Coupling
Abstract: This article discusses how one can effectively couple light from the fundamental mode of a multimode fiber into a certain higher-order mode. Mode conversion effects in Fibre Bragg Gratings (FBGs) are widely exploited in applications such as sensing and fibre lasers. Abstract— The spectral characteristics of superstructure fiber Bragg gratings are analyzed numerically based on the coupled mode theory, simultaneously taking into account the counterdirec-tional guided mode coupling, codirectional and counterdirectional claddings mode coupling. Transmission spectra of inhomogeneous and asymmetric FBGs that have been inscribed with focused ultrashort pulses.

What is a spiral fiber Bragg grating
A fiber Bragg grating (FBG) is a microstructure typically a few millimeters in length that can be photo inscribed in the core of a single mode fiber. This is done by transversely illuminating the fiber with a UV laser beam and using a phase mask to generate an interference pattern in. Typically, the perturbation is approximately periodic over a certain length of e. The reflected wavelength, known as the Bragg wavelength, is determined by the period of.
