Abstract: (1022 Views)
In this paper, a uniform Fiber Bragg Grating (FBG) have been simulated by using the coupled differential equations and the transfer matrix method. Different approaches for improving FBG characteristics such as changing length, chirping and apodization have been studied. The Cosine, Raised-Cosine and Tanh functions have been used to apodization. Finally, considering the advantages and disadvantages of these approaches, a chirped apodized fiber Bragg grating with Raised-Cosine apodization profile has been simulated and designed. In this type of FBG, without reducing reflecitivty, in comparance to the uniform FBG, the sidelobe-strength has been reduced around the ranges of 75%. This FBG, which has an optimized design in length, has a maximum reflectivity of 100%, a very low sidelobe-strength of 10-3% and a suitable bandwidth of 0.298nm. The presented FBG has the potentiality to be applied in communication systems such as filters and sensors.
