We experimentally demonstrate a three-dimensional photonic crystal (3D PC) nanocavity in a 〈110a〉-layered diamond structure with a quality factor (Q-factor) of 12800 at a wavelength of 1.1 μm. The observed Q is 1.2 times higher than that of a 3D PC nanocavity in a woodpile structure with the same in-plane size and the same number of stacked layers. This result indicates the potential importance of the 〈110a〉-layered diamond structure for getting high Q 3D PC nanocavities within a limited in-plane space.
