A new publication from Opto-Electronic Sciences; DOI 10.29026/oea.2025.240114, discusses an ultra-high-Q photonic crystal nanobeam cavity for etchless lithium niobate on insulator (LNOI) platform.

These are the so-called photonic time crystals. It is their electromagnetic properties that change with time. There are many challenges when trying to create a three-dimensional photonic crystal.
