ABSTRACT
Air-core photonic crystal waveguides with cylindrically periodic index variations are first proposed, thereby making low-index cores. The proposed waveguide can provide numerous novel properties including large or small effective areas. Based on two computational analyses of the finite-difference time-domain and finite difference method for accurate and cross-verified results, sizing the core hole provides a decent way to control the effective area. Also, it is noticed that the effective areas at the longer wavelength generally result in larger values for each different hole radius.
