integrated photonic devices and chips | ALIGN lab | Advanced Laboratory of Integrated & Guided Nanophotonics

introduction

The evolution of optics from bulky, table-top setups to integrated planar circuits is revolutionizing how we manipulate light. Integrated photonics allows for the routing, modulation, and detection of light within millimeter-scale footprints, bridging the gap between fundamental physics and practical, scalable technologies. By bringing exotic optical phenomena down to the chip level, we can engineer complex electromagnetic environments that are highly stable, robust, and reproducible.

This research direction focuses on the physical realization and architectural optimization of compact photonic systems. We bridge novel theoretical concepts with advanced nanofabrication, aiming to translate fundamental discoveries into functional hardware platforms that define the next generation of optical technology.

significance & applications

On-chip integration drastically reduces the footprint, power consumption, and manufacturing cost of optical systems while enhancing their mechanical stability and scalability. The potential applications are extensive, driving innovations in high-capacity data center interconnects, solid-state LiDAR for autonomous vehicles, portable lab-on-a-chip biosensors, and scalable quantum photonic processors.

research focus

on-chip integration of novel phenomena: translating emerging optical physics and fundamental principles into compact, chip-scale device architectures. (e.g., integrating (Wu et al., 2022) on-chip (Wu et al., 2023))
heterogeneous integration and chiplets: combining disparate material platforms and functional photonic chiplets through advanced packaging to overcome the performance and fabrication limits of monolithic systems.
exploratory integration of advanced materials: investigating and evaluating the compatibility, stability, and potential of next-generation functional materials within standard on-chip fabrication processes. (e.g., (Wu et al., 2021; Huang et al., 2023; Wu* et al., 2024))
prototype miniaturization and integration: transforming bulky, macro-scale experimental setups and abstract theoretical models into highly integrated, portable physical devices.

The integrated chip with temporal Talbot effect.

We also aim to employ early theoretical works into integrated nanodevices (nanostructure, thin-film device, metasurface), chips (hybrid & novel materials), and circuits (networks with certain topology) with our newly developed technique and in collaboration with our sister labs and colleagues around the world.
