Telecommunications underpin many sectors of modern life and especially the growing digital economy. The rapid growth of the telecommunications transmission capacity along with the significant reduction of the cost per bit has enabled development of new technologies and business models which revolutionised everyday life. The telecommunications backbone is formed by fibre optic communications enabling transmission of vast amount of data between virtually any points on the Earth. Multiplication of the fibre optic communications transmission capacity in the past decades have been provided mostly by several technological breakthroughs, such as employment of Erbium-doped fibre amplifiers or coherent receivers. The next significant advancement providing a revolutionary shift in fibre optic communications could be employment of multi-band transmission utilising the whole bandwidth available in modern optical communication fibres. Multi-band optical communications have potential to five-fold the transmission capacity without need to deploy new transmission fibres thus significantly reducing the costs. However, the key challenge for employment of multi-band transmission is lack of suitable optical amplifiers able to operate in the wavelength bands of interest and across several bands simultaneously.This project, Interferometric and Multiband optical Parametric Amplifiers for Communications (IMPAC), will provide the key advances necessary for fibre optic parametric amplifiers (FOPA) to enable EDFA-equivalent signal amplification in all wavelength bands appealing for multi-band communications (O, E, S, C, L) and with bandwidth in excess of 100 nm, potentially up to 200 nm. In IMPAC I will:1. Create a fully autonomous and robust polarisation-insensitive (PI) FOPA with high net gain >20dB and low polarisation-dependent gain <0.5dB across a record wide bandwidth >100nm.2. Pioneer interferometric FOPAs rejecting unwanted FWM products to double available gain bandwidth or to 'eliminate' nonlinear crosstalk with suppression of ~20dB.3. Significantly (by a factor of 10) reduce the signal noise attributed to the stimulated Brillouin scattering mitigation, whilst allowing for a wide FOPA gain bandwidth of at least ~100nm.4. Pioneer a PI-FOPA with gain tuneable across O/E/S bands for signal and pump amplification, and consequently create the first-ever distributed PI-FOPA in SSMF.5. Devise the 'next generation' PI-FOPA combining the project achievements in terms of gain bandwidth, low noise figure, rejection of unwanted FWM and SBS mitigation to facilitate operation across a bandwidth up to 200nm with performance superior to commercial EDFAs.

电信支撑着现代生活的许多领域，尤其是不断增长的数字经济。电信传输容量的快速增长以及每比特成本的显着降低促进了新技术和商业模式的发展，彻底改变了日常生活。电信主干网由光纤通信构成，几乎可以在地球上的任何点之间传输大量数据。过去几十年来，光纤通信传输容量的倍增主要归功于多项技术突破，例如掺铒光纤放大器或相干接收器的使用。光纤通信领域的下一个重大进步可能是利用现代光通信光纤中可用的整个带宽进行多频带传输。多频段光通信有潜力将传输容量提高五倍，而无需部署新的传输光纤，从而显着降低成本。然而，使用多波段传输的关键挑战是缺乏能够在感兴趣的波段和同时跨多个波段工作的合适的光放大器。这个项目，用于通信的干涉和多波段光参量放大器（IMPAC），将提供光纤参量放大器 (FOPA) 所需的关键进步，可在所有波长带中实现相当于 EDFA 的信号放大，从而满足多频带通信（O、E、S、C、L）的要求，并且带宽超过100 nm，可能高达 200 nm。在 IMPAC 中，我将：1。创建完全自主且稳健的偏振不敏感 (PI) FOPA，在创纪录的宽带宽 >100nm 上具有 >20dB 的高净增益和 <0.5dB 的低偏振相关增益。2。先锋干涉式 FOPA 可抑制不需要的 FWM 产品，使可用增益带宽加倍或通过约 20dB 的抑制“消除”非线性串扰。3。显着（减少 10 倍）减少因受激布里渊散射抑制而产生的信号噪声，同时允许至少 ~100nm 的宽 FOPA 增益带宽。4。率先推出增益可在 O/E/S 频段可调的 PI-FOPA，用于信号和泵浦放大，从而在 SSMF.5 中创造出有史以来第一个分布式 PI-FOPA。设计“下一代”PI-FOPA，结合增益带宽、低噪声系数、抑制不需要的 FWM 和 SBS 抑制方面的项目成果，以促进在高达 200nm 的带宽上运行，性能优于商用 EDFA。
