High dimensional meta-devices: classical to quantum

Meta-surfaces are composed of an array of artificial nanostructures. The electromagnetic wave can be manipulated with its phase, polarization, and amplitude at will. Nowadays, the demand for photonics is extended from classical to quantum optics. With the advent of the post-Moore era, the fabrication technology of the semiconductor industry has faced the problem of the physical limitation approach. They have urgently needed to find out new methods and new physics to break through this dilemma. Quantum optics technology is the most suitable solution for this situation. Here, the design, fabrication, and application of the novel optical meta-devices are reported from classical to quantum optics in this talk. The meta-lens array with achromatism is used to demonstrate a light field system for imaging and sensing. The integrated meta-lens array is used to demonstrate a high dimensional quantum light source chip with excellent performance of quantum fidelity.
