A series of microcavities in circular photonic crystal slabs are studied in this paper. It is shown that high quality factors can be obtained for such microcavities. For a cavity with three inner layers of air holes missing, Q factor larger than 10 5 can be obtained. It is also worth noting there ex
## Abstract Devices based on twoβdimensional (2D) photonic crystals (PCs) are typically realized as 3D structures consisting of an array of holes (or rods) vertically etched through a slab waveguide. The existence of holes in a slab waveguide may induce strong radiation losses to the slab claddings
