(In-person) Title: Photon-Counting Receivers for Future Optical Wireless Communications

Abstract: Optical wireless communication (OWC) offers several complementary advantages over radio-frequency wireless networks, including access to a vast available spectrum. As a result, OWC is expected to play an important role in forthcoming sixth-generation wireless communication networks. Although significant progress has been made in OWC over the past decades, outages caused by intermittently low received optical power remain a key limiting factor for widespread deployment. In this talk, the potential of photon-counting receivers is discussed as a promising solution to overcome this limitation. The main factors that limit their performance are also introduced, along with approaches for modelling them. Finally, a comprehensive performance-enhancement framework is proposed to address these issues, and selected open problems for future research are presented.

(In-person) Title: Performance Enhancement in Optical Wireless Communication via Diversity, Advanced Receiver Design, and Mitigation Techniques

Abstract: Significant advancements in optical wireless communications (OWC) techniques in recent years have positioned it as a leading complementary technology to extend future-generation wireless connectivity from underwater to space. Over the years, OWC has seen substantial technological improvements addressing fundamental challenges such as channel impairments, limited transceiver bandwidth and restricted mobility due to the directional nature of optical transmission. The availability of high-spatial-density optical sources at multiple wavelengths has enabled the development of spatial and wavelength diversity techniques, which are essential for overcoming limitations in system bandwidth. However, designing robust diversity schemes that can effectively operate under channel impairments remains challenging, requiring careful system design and advanced mitigation strategies to address unavoidable spatial and temporal interferences. Furthermore, the etendue imposes a trade-off between the field of view and receiver optical gain, which are critical for achieving wider mobility and a power-efficient receiver design.  

This talk presents an overview of optical spatial diversity techniques, including imaging and non-imaging approaches, and various practical demonstrations.  The talk will also highlight the spatial and temporal interference challenges and their joint mitigation approach using advanced mitigation strategies, such as the use of artificial neural networks.  The talk will also highlight approaches for designing wide field-of-view receiver designs based on fluorescent antennas to overcome the Eendue, along with methods for implementing wavelength-diversity receivers using these devices.
