Abstract
As more demands are made on telecommunications and other applications of photonics such as sensing, demand for the complexity and functionality of the interconnecting devices increases. Fibre Bragg Gratings (FBG) for optical filters and switching are an inherent part of such systems. In this paper we report the experimental study of gain of telecommunication Erbium Doped Fiber Amplifier (EDFA). For particular pump power, the gain of Erbium Doped Fiber Amplifier for the wavelength range of 1529 nm - 1559 nm was measured and found that the gain of the Erbium Doped Fiber Amplifier is very uneven exhibiting peaks with different widths around 1532 nm and 1550 nm. On analysis of the results, filter of desired characteristic is suggested which could support for flattening the gain of EDFA for fixed pump power, so that the EDFA could be used for WDM applications. Three parameters which described the apodised grating profile were used to define the search space and the transfer matrix method is used to numerically evaluate the transmission spectrum.
