High Dimensional Meta Devices from Classical to Quantum (NoTu3D.1)
Presenter: Din Ping Tsai, The Hong Kong Polytechnic University

High dimensional quantum meta-device for entanglement light source is demonstrated by a 10 x 10 meta-lenses array. Two, three, and four-dimensional two-photon path-entanglement with different phase-coded meta-lenses are shown.

Tunable Bound State in the Continuous with Metasurfaces and Anisotropic Medium (NoTu3D.2)
Presenter: Kuo-Ping Chen, National Chaio-Tung University

In this work, we have demonstrated the tunable bound state in the continuum (BIC) and quasi-BIC with asymetric structure design and temperature control.

High Dimensional Quantum Light Source with Meta-lens Array (NoTu3D.3)
Presenter: Xiaoyuan Liu, The Hong Kong Polytechnic University

We demonstrate a 100-path entangled photon-pair source by integrating a meta-lens array with a nonlinear crystal, which shows promise for quantum-optical technologies with high-dimensional entanglement and multiphoton-state generation.

Giant Third-Harmonic Dichroism Driven by Quasi-BIC in Chiral All-Dielectric Metasurfaces (NoTu3D.5)
Presenter: marco gandolfi, Istituto Nazionale di Ottica Consiglio Nazionale delle Ricerche Sezione di Brescia


We develop a new approach based on quasi-BICs to develop chiral metasurfaces exhibiting nonlinear circular dichroism (up to 99.9%) and high conversion efficiency. Tuning mode interference allows selective linear and nonlinear circular dichroism.

Dimerzied metasurfaces as a platform for cavity optomechanics (NoTu3D.6)
Presenter: Jan Meyer, Laboratory for Emerging Nanometrology (LENA),Langer Kamp 6a/b, 38106 Braunschweig, Germany

We present a novel platform for cavity optomechanics based on dimerized metasurfaces with high aspect ratio. We illustrate that these structures are promising to reach the strong coupling regime and present first experimental results.
