05/01/2024 Our latest work on "Spectral engineering of optical microresonators in anisotropic lithium niobate crystal" published in Advanced Materials(inside front cover)!

We demonstrate arbitrary spectral engineering of optical microresonators in the anisotropic lithium niobate platform using gradient-design photonic crystal rings (PhCR), and construct a “mirror” in the synthetic frequency dimension based on an actively-modulated gradient-PhCR. Our work opens up new paths toward arbitrary control of electro-optic comb spectral shapes and exploration of novel physics in the frequency degree of freedom. Congratulations to Ke and Yikun!
