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.

电信是现代生活的许多部门，尤其是数字经济的发展。电信传输能力的快速增长以及每位成本的大幅降低，使得开发了彻底改变日常生活的新技术和商业模式。电信主干是由光纤通信形成的，可以在地球上几乎任何点之间传输大量数据。在过去几十年中，光纤通信传输能力的乘法主要是通过几个技术突破提供的，例如使用Erbium掺杂纤维放大器或相干接收器。提供光纤通信革命性转变的下一个重大进步可能是利用现代光学通信纤维中可用的整个带宽的多波段变速器的使用。多波段光学通信有可能在不需要部署新的传输纤维的情况下可能会大大降低成本。但是，使用多波段传输的关键挑战是缺乏能够在感兴趣的波长频段和几个频段中运行的合适的光学放大器。此项目，这些项目，干预和多型光学参数放大器的通信（IMPAC）将提供光学及时启动amentemplaimplifier的关键进展（IMPAC）。波长带有多波段通信（O，E，S，C，L）的波长频段，带宽超过100 nm，可能达到200 nm。在Impac I将：1。在创纪录的宽带宽> 100nm.2上，创建一个完全自主且强大的极性不敏感（PI）FOPA，净增益高> 20dB，低极化依赖性增益<0.5dB。先锋干涉测定法拒绝不需要的FWM产品，以双重可用增益带宽或“消除”非线性串扰，抑制〜20dB.3。显着（以10倍）减少了归因于刺激的布里鲁因散射缓解的信号噪声，同时使FOPA增益带宽至少为〜100nm.4。先驱A pi-fopa具有可调节的跨O/E/S谱带的Pi-Fopa，以进行信号和泵扩增，因此在SSMF.5中创建了有史以来第一个分布式Pi-fopa。根据增益带宽，低噪声图，不需要的FWM和SBS缓解措施的“下一代” Pi-fopa结合了项目成就，以促进在带宽至200nm的带宽，并且性能优于商业EDFAS。
