主讲内容：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.
