Abstract: Language agents, designed to interact with their environment and achieve goals through natural language, traditionally rely on Reinforcement Learning (RL). The emergence of Large Language Models (LLMs) has expanded their capabilities, offering greater autonomy and adaptability. However, there's been little attention on augmenting the morality of these agents. RL agents are often programmed with a focus on specific goals, neglecting moral consequences, while LLMs might incorporate biases from their training data, which could lead to immoral behaviours in practical applications. This presentation introduces our latest research endeavors focused on enhancing both the task performance and ethical conduct of language agents involved in intricate interactive tasks. For RL agents, we use text-based games as a simulation environment, mirroring real-world complexities with embedded moral dilemmas. Our objective thus extends beyond improving game performance to developing agents that exhibit moral behaviour. We first develop a novel algorithm that boosts the moral reasoning of RL agents using a moral-aware learning module, enabling adaptive learning of task execution and ethical behavior. Cconsidering the implicit nature of morality, we further integrate a cost-effective human-in-the-loop strategy to guide RL agents toward moral decision-making. This method significantly reduces the necessary human feedback, demonstrating that minimal human input can enhance task performance and diminish immoral behaviour. Shifting focus to LLM agents, we begin with a comprehensive review of morality in LLM research, scrutinizing their moral task performance, alignment strategies for moral incorporation, and the evaluation metrics provided by existing datasets and benchmarks. We then explore how LLM agents can improve their moral decision-making through reflection. Our experiments, conducted within text-based games, show that integrating reflection enables LLM agents to make more ethical decisions when confronted with moral dilemmas.

IEEE EDS DISTINGUISHED LECTURER SEMINAR: GRAPHENE AND WSE2-BASED SELF-DRIVEN PHOTODETECTORS (29 May 2024)(8 April 2024)

Abstract: The advent of graphene and other 2D materials offers great potential for optoelectronics applications. Various device structures and novel mechanisms have been proposed to realize photodetectors with unique detecting properties. In this talk, we report the results for two metal-semiconductor-metal (MSM) photodetectors with asymmetric contacts based on graphene and a member of the transition metal dichalcogenides family, WSe2, which enable the self-driven characteristics that is absent in conventional MSM photodetectors. In the first configuration (Au-WSe2-Graphene), both the Au-WSe2 and WSe2-Graphene contacts are formed by PDMS-mediated dry transfer techniques, with two asymmetrical van der Waals contacts formed to yield the proposed structure. When the device is under illumination at a wavelength of 650 nm, a large photocurrent is measured. Further, an open-circuit voltage Voc and a short-circuit current Isc are clearly observed, indicating the self-driven properties of the MSM photodetectors. The Voc and Isc can also be tuned by a back-gate voltage, which results from the tunable Schottky barrier height along with the gate tunable carrier concentration in WSe2. In the second device configuration (Au-WSe2-Au), the same type of Schottky barrier is formed while the contact lengths of the two Au-WSe2 junctions are designed and fashioned to be different to result in a net Isc. This self-driven photodetector with asymmetric contacts has great potential for low-power or even powerless operation. Combining the wide spectra covered by various 2D materials with different bandgaps, it is expected that the self-driven 2D-materials-based photodetectors can supplement the current mainstream silicon and compound semiconductor-based photodetectors which can only detect a narrow range of the optical spectrum.

IEEE MTT-S DISTINGUISHED MICROWAVE LECTURE: MICROWAVE PHOTONIC RADARS: WHAT CAN PHOTONICS BRING TO RADARS? (8 April 2024)
As the only method for all-weather and long-distance target detection and recognition, radar has been intensively studied since it was proposed, and is considered as an essential sensor for future intelligent society. In the past few decades, great efforts have been devoted to improving radar’s functionality, precision, and response time, of which the key is to generate, control, and process a wideband signal at a high speed. Thanks to the high frequency, large bandwidth, low loss transmission, and electromagnetic immunity provided by modern photonics, implementation of the radars in the optical domain can provide better performance in terms of resolution, coverage, and speed which may not be achievable using traditional, even state-of-the-art electronics. In this talk, I'll give an overview of the photonic technologies that are currently known to be attractive for radars. System architectures and their performance that may interest the radar society are emphasized. Emerging technologies in this area and possible future research directions are discussed.
