Quantum information processing needs be realized on a chip for practical applications, and therefore various optical microstructures will be developed and integrated on a single chip. In history, we prepared the first optical quantum circuit on lithium niobate (LN) chips with optical superlattices and other microdevices. Recently we demonstrated a 100-path parametric down-conversion photon-pair source by integrating a metalens-array with a nonlinear crystal BBO, which shows promise for high-dimensional entanglement and multiphoton-state generation.

Metasurfaces and metamaterials are emerging as advanced tools to control the degrees of freedom of light (e.g. amplitude, phase, polarization, spectral response, and more) and can be used to significantly enhance light-matter interactions. As such, they hold the promise of becoming key components in opto-electronic devices and systems. In this talk I will describe our recent progress in the field. Some specific examples are the enhancement of interactions between light and thin layers of materials, such as hyperbolic metamaterial cavities and other nanostructures, leading to enhanced light emission and enhanced photodetection. I will also discuss some of the limitations and the opportunities of metalenses in imaging applications. Finally, I will demonstrate tunable metasurfaces via mechanisms such as the electro optic effect and MEMS.

We initiate this talk dedicated to commemorating the 30th anniversary of the birth of optical vortices (OVs). It covers the main contents from fundamental theory, recent progress to important applications of OVs. In this talk, firstly, we review origin of the orbital angular momentum (OAM), and give two kinds of typical optical vortices which contain optical singularity: OAMs and cylindrical vector beams (CVBs). We further introduce novel development in terms of transverse spin and transverse OAM as well as optical skyrmions, which is a topological optical spin distribution due to the coupling between spin and OAM of light. In the applications wise, we mainly focus on the examples of OVs for optical tweezers, optical imaging and optical communications.

Femtosecond laser nanofabrication provides a new technical avenue towards micro-nanodevices. Comparing with the currently available nanofabrication approaches including photolithography, nanoimprinting, focus ion beam, it is unique in the three-dimensional (3D) processing capability and applicability to hard-processing materials. These make new concepts, stero-integrated optics and special optoelectronic devices possible. The talk will introduce our recent research progress along these lines, including quantum chips, micro-optical integrated system and sapphire optical devices.
