Abstract

In this paper we discuss the use of photonic crystal fibers (PCFs) as discrete devices for simultaneous wideband dispersion compensation and Raman amplification. The performance of the PCFs in terms of gain, ripple, optical signal-to-noise ratio (OSNR) and required fiber length for complete dispersion compensation is compared with conventional dispersion compensating fibers (DCFs). The main goal is to determine the minimum PCF loss beyond which its performance surpasses a state-of-the-art DCF and justifies practical use in telecommunication systems.

摘要

在本文中，我们讨论了将光子晶体光纤（PCF）用作离散器件以同时进行宽带色散补偿和拉曼放大。将光子晶体光纤在增益、纹波、光信噪比（OSNR）以及完全色散补偿所需光纤长度方面的性能与传统色散补偿光纤（DCF）进行了比较。主要目标是确定光子晶体光纤的最小损耗，超过该损耗其性能将超越最先进的色散补偿光纤，并证明其在电信系统中的实际应用价值。
