Description | The PHOS project relates to the application of optical phase conjugation systems in the transmission of data signals in fibre optic communications. Through experimental demonstrations, we have shown that phase conjugation can substantially improve the quality of signals at the point of detection. Furthermore, PHOS has aimed to demonstrate how optical processing systems, i.e. systems that allow processing of data signals in an optical form without requiring an electronic processor, can be made practical for use in real-world applications. To this effect, we have developed a black-box prototype that performs wavelength conversion (the physical process underlying optical phase conjugation) and can be operated without any prior knowledge of the physical processes that take place in it. The prototype has been fully packaged and a suitable software has been developed to offer a suitable level of abstraction to the user. We believe that this represents one of the most complex optical prototype sub-systems ever attempted, requiring automated control of a number of off-the-shelf optical components. At the later stages of the project, we have explored in depth the onset of deleterious parametric frequency components and developed techniques for combating them. These components can give rise to crosstalk (i.e. interference with other (wanted) frequency components that compromise their quality) and severly limit the practicality of optical nonlinear systems. The technique developed in PHOS, which we have since patented, relies on dividing the signal propagation in the nonlinear device into two halves, and using the second half to "undo" the nonlinear effects responsible for the generation of undesired components during propagation in the first half. Other contributions that have resulted from PHOS relate to the exploitation of new frequency bands for optical communications and detailed studies into the effects of fibre birefringence and the stimulated Brillouin scattering on the performance of nonlinear optical devices. |
Exploitation Route | The core objectives of the project have been met, and significant contributions to the transmission and processing of optical signals have been achieved. Nevertheless, it should be noted that the project has been affected severely by the pandemic, and as a result several of the activities that had been initially planned in order to generate and accelerate the project's impact had either to be put on hold or carried out on an ad hoc manner and virtually, which has admittedly been short of ideal. The development of the wavelength converter prototype in the project has offered a first-class opportunity to disseminate the project technology to outside users. Following the end of the project, we will continue to engage with the industrial partners of the project to obtain feedback and offer trials of the prototype in their testbeds. We will consult with our academic collaborators, especially those specialising in network control and management to explore routes for further development. We have already carried out an (online) presentation of the prototype at the world's greatest optical communications conference (OFC). Additionally, we anticipate that the patent that has been filed through the research in PHOS will offer opportunities for further engagement both with industrial and academic partners, and will expand the application field of optical signal processing. |

Description | Implementations studied within PHOS were developed in a prototype through a project co-funded by an external (undisclosed) sponsor and the Univ. of Southampton's EPSRC Impact Acceleration Account.The prototype was delivered to the sponsor and is being used in their laboratories. One patent has been filed from the research carried out in PHOS and we will next engage with industrial partners to understand their interest in getting access to the technology. The findings from these project have led to further research, demonstrating wavelength conversion that is free from any spurious crosstalk effects that would otherwise be present. |
