Welcome to the lab website!

lab introduction

The Advanced Laboratory of Integrated and Guided Nanophotonics (ALIGN) led by Prof. Jiaye WU at the City University of Hong Kong (Dongguan), focuses on the linear and nonlinear light matter interactions in integrated and nanophotonic platforms.

Research directions: Ultrafast light-matter-interactions, epsilon-near-zero and near-zero-index photonics, fibre optics, fibre laser, optical waveguide network design, functional thin film and metadevice design, non-Hermitian optics, integrated optics, advanced semiconductor optical materials.

Call for collaboration: Cross- and multidiscipline research on semiconductor optics (micro- nano-devices), electro-optic integration, MEMS, photonics-related lab-on-a-chip; biophotonics; photonic computing; smart photonic design (AI for photonics) and photonic design for AI.
