Abstract

With a view to enhancing the performance of all-fiber amplifier using Er⁺³-doped triangular-lattice photonic crystal fiber (PCF), we performed a detailed study of the amplifying characteristics of the PCF host by varying all associated parameters towards achieving high gain and lower optimum doped fiber length (minimum length required to get the maximum level of gain). A finite difference (FD) mode- convergence analysis is used to determine the modal propagation characteristics in the structure, which is then used to solve a standard propagation and population rate equation. Our results show that a spectral gain of the amplifier as high as 51 dB and that too over a short length ~2.4 m of the active fiber is achievable by optimizing the gain dependent parameters and the transverse geometry of the fiber. Aimed at field-deployment of the amplifier as inline component, we optimize splicing/coupling loss (considering the mismatch of fundamental modes only) of this all-fiber device. Notably, the splice loss with standard telecom-grade SMF-28 fiber is minimized through an improved mode-matching of the design. These results are new in fiber amplifier research and would make useful contribution to realize high-performance PCF-based amplifiers and devices.
