Space-division multiplexing (SDM)
Space division multiplexing (SDM) in multi-mode and multi-core fibers has been a major topic in optical fiber communications research since the beginning of the last decade. SDM research aims at exploiting spatial diversity in optical transceivers, fibers, amplifiers, routers etc. to increase the per-link transmission capacity while reducing cost, complexity, and eventually energy consumption.
This workshop intends to gather experts in the field to establish an overview of the current state of SDM research with a focus on:
• Integrated transceivers and components for SDM
• Advances in SDM fiber design, modeling and analysis of novel propagation effects
• An industry perspective on SDM
The workshop further aims at stipulating an open discussion between panelists and attendees on the challenges and opportunities envisaged in the deployment of massive parallel transmission systems.

Nonlinearity compensation or advanced coded modulation schemes to achieve fibre's ultimate transmission limit?
Optical fibre transmission capacity is still unknown. However, what we know for sure is that fibre capacity is theoretically achievable using forward error correction in combination with one of these two alternative approaches: i) nonlinearity compensation (NLC); ii) coded modulation. Digital nonlinearity compensation schemes have proven to be extremely effective when it comes of suppressing nonlinear distortions on the received signal, but is limited by high computational complexity. On the other hand, nonlinearity-tailored coded modulation schemes can be in general implemented with a lower complexity than NLC but they have not so far yielded dramatic information rates improvements. The question is then which of these two approaches is more effective in terms of performance-complexity tradeoff?
In this workshop, speakers will share their views on the future of approaching capacity and the prospects of performance-complexity tradeoff for optical fibre communication system.

Biophotonic imaging roadmap 2021
In the 21st century, biomedical imaging presents a series of new development trends: breaking the diffraction limit, high-speed, deep three-dimensional, label-free imaging. In association with other novel technologies such as multi-modality probes, new light sources, detectors, lightfield manipulation, computational imaging, and other related technologies, biophotonic imaging provides new solutions and insights for many applications.
Arising from asking questions to analyzing questions, this workshop will give examples of the cutting-edge biological imaging technologies and their applications, and discuss how we can expand the application of biological photonics imaging in interdisciplinary fields with these new tools. In the meantime, we will address how biophotonics field can better respond to our national calls, to solve the challenging international or regional life science and medicine problems.

Heterogeneous Photonic Integration on Silicon
Silicon has become the platform of choice for large-scale photonic integration. Its compatibility with the mature CMOS processing technology offers the well-known advantages of scalability, low-cost at high-volume, and high yield. Despite its success during the last 20 years in both academia and industry, further improvement on functionalities and performances of silicon photonic circuits beyond the limitations posed by the intrinsic material capabilities of silicon is needed for photonics. Improvements in silicon photonics for efficient light generation, optical amplification, high-speed and efficient optical modulation, low-noise high quantum-efficiency high-speed photodetectors, nonlinear photonic devices and integrated quantum photonic applications may be brought about with the use of different materials integrated on silicon. Heterogeneous integration technology can bring together silicon and other materials with better optical properties. Combining the best of different material systems, it holds the potential to realize full functioning photonic circuits. This workshop will focus on recent advances and future developments of heterogeneous photonic integration on silicon in all related aspects including fabrication processes, discrete devices, integration technologies, novel two-dimensional materials on silicon etc.

Co-integration of photonics and electronics
Co-integration of photonics and electronics has received considerable attention in recent years for the advantages of shrunk footprint, lower cost, and reduced power consumption. Silicon photonics is a platform on which photonics and electronics can be integrated, by leveraging standard fabrication processes in the microelectronics industry. This workshop will provide an open forum for speakers and audience to discuss the possible technologies to merge photonics and electronics on chip and forecast potential applications. We will first review the current status of co-integration with an emphasis on monolithic integration on silicon. Then we will talk about the desired performance metrics of building blocks, required fabrication processes, and mass production issues. Finally we will brain storm the possible roadmap for future technology development and the emerging applications.

Light: Science & Application workshop in Quantum Photonics
Photonics is vital in quantum information processing. While quantum key distribution (QKD), where secret key is negotiated through quantum channel, continues its strong momentum and fast development, quantum secure direct communication (QSDC), where secret information is transmitted directly through quantum channel, is witnessing a transformation from a mere theoretical scheme to a fully developed practical protocol. Sponsored by the world-leading optical journal, Light, Science & Applications, the quantum photonics workshop features seven invited talks on the recent progress in QKD, QSDC and photonic chip for scalable quantum information processing. A 15-user quantum networks with QSDC, and the world first experimental endeavor to study the feasibility of QKD and QSDC from the 36000 km SJ-20 geosynchronous orbit satellite will be reported in the workshop. Important issues of quantum communication within the larger arena of the communication world will be touched in the workshop.
