报告题目：Evolution of Optics: From Fundamental Science to Engineer Advance Systems
Optics primarily has two major branches: physical and geometrical. The former deals with the nature and properties of light itself, while the latter covers the principles that govern the image-forming properties of optical components (like lenses, mirrors, etc.) by using light. Initially, the term optics was used only for the eye and vision. However, with the development of lenses and other devices for aiding vision, the meaning of the term optics eventually became broadened to cover any application of light, even though the ultimate receiver is not the eye but a physical detector, such as a photographic plate or a television camera. In the 20th century, optical methods came to be applied extensively to regions of the electromagnetic radiation spectrum not visible, such as X-rays, ultraviolet, infrared, and microwave radio waves, and to this extent, these regions are now often included in the general field of optics. In the talk, the speaker will briefly discuss the fundamental concepts of electromagnetic waves and optics and enlighten the optical components' image-forming properties using light. He will highlight the design considerations for integrating multiple elements to achieve advanced aberration-free optical systems. Design considerations can broadly be used in optical engineering, encompassing the physical phenomena and technologies associated with the generation, transmission, manipulation, detection, and utilization of light. Optics solves problems and designs and builds devices such as lenses, microscopes, telescopes, lasers, sensors, fiber optic communication systems, and optical disc systems. Finally, the speaker will briefly shed light on the latest trends and futuristic potential in flat-optical engineering and present a few highlighted works of his research group.
报告题目：On-chip Optics: Promising Advanced Device to Systems Level Solutions
Reducing the footprint of conventional optical devices/systems is inevitable to meet the ever-growing demands of compactness, high efficiency, and better performance. Metasurfaces-based devices promise an enormous potential to realize futuristic and efficient ultra-compact optical systems by bringing their footprint to the chip scale. They offer better functionality with ultra-compactness, making them feasible for on-chip integration. The recent establishment of companies like Metalenz (https://metalenz.com/) is evidence of the industrial acceptance of these meta-devices. However, the mass-scale adoption of metadevices will require efficient design procedures (in terms of time and cost), real-time tunability, and the capability of integrating multiple functionalities into a single chip (for an advanced level of compactness), etc. The talk will cover the latest trends in the design and development of state-of-the-art metadevices and meta-optical systems. The speaker will present a few of his highlighted works along these lines and explain the design strategies to achieve the next level of multi-functionality and tunability. He will also explain the real-time utility of such metadevices for bioimaging and biosensing.
