Speech Title: Modelling and Simulation of Semiconductor Optoelectronic Devices
Abstract: Based on the analyses and calculation of the optoelectronic properties of bulk and MQW III-V compound semiconductors with zincblende structure and direct-bandgap, a comprehensive quasi-3D model for the analysis of the static and dynamic behaviors of semiconductor optoelectronic devices, such as semiconductor optical amplifiers (SOA’s), laser diodes (LD’s), electro-absorption modulators (EAM’s), and their integrations, is developed by separating a 3D problem into 2D cross-sectional and 1D longitudinal modules. The model considers the material properties and the traveling-wave effects in very details. Both time-domain and frequency-domain properties of a wide variety of semiconductor devices can be simulated using this model. To demonstrate the capabilities of the model, some simulation results are presented as examples.

Speech Title: Evolution and Challenge of Algorithms and Chips in Long Haul Optical Transmission Systems
Abstract: Coherent optical communication algorithms and chips have been the key driving force behind the rapid evolution of long-haul optical transmission systems in the past two decades. This paper reviews the evolution process of coherent optical algorithms and chips for long-haul optical transmission, and provides a detailed introduction to key digital signal processing algorithms that are of concern in ASIC design. It also discusses the implementation constraints of low complexity and low-power chips on high-performance algorithm design. For the future, a new spatial division multiplexing system architecture based on multi-fiber in optical cables has been proposed for the continuous evolution of optical transmission systems, along with corresponding proposal for coherent optical modules, algorithms and chips.

Speech Title: Integrated Photonics for Quantum Technologies

Abstract：Quantum information technologies are gathering attention as the next generation information technology, offering highly efficient computational techniques for crucial areas. Such systems require physical carriers of quantum information, among which photons are notable candidates. Photon allow for room-temperature experiments, inter-device communications, and fast computation with a relatively small number of quanta (quantum supremacy). However, quantum information processing devices have traditionally been constructed with free-space optics, which poses challenges for scale up. To address this, attempts to construct photonic quantum information devices using tiny optical waveguide circuits manufactured on silicon chips began around 2010. These devices, known as silicon photonics, were originally developed for optical communication devices and enable the miniaturization and stabilization of photonic quantum systems [1].

We have developed various quantum information devices based on silicon photonics, such as sources of quantum light [2- 6] and photonic quantum circuit [7-10] toward the realization of a fully integrated system of quantum computing on a silicon wafer. In this talk I will review such developments as well as the status and challenges.

Speech Title: 6G Evolves from Communication to XaaS

Abstract：5G’s large scale deployment and commercialization shows that the capabilities beyond communication is necessary for the network to provide a turn-key solution for vertical industry customers, e.g. positioning, computing, storage and AI. Towards 2030, more and more new use cases and scenarios demands integration of communication, sensing, computing, data and AI. To extend the business scope of the mobile operators, the 6G network’s design target is to enable these new capabilities as a service, e.g. sensing as a service, computing as a service, data as a service, and AI as a service. To achieve this, a holistic service based architecture is introduced to support dynamical orchestration and integration of functions and physical resources and provide customized and personalized network deployment in a on demand manner. From the end to end protocol design perspective, the protocol plane are expanded from the existing communication plane to support computing plane, data plane and AI plane, and thus enable X as a service.
