Modeling and design of irregularly arrayed waveguide gratings
Optics Express, 2007 In this paper we propose a concept of irregularly arrayed waveguide gratings (IAWGs). By replacing regularly arrayed waveguides of conventional AWGs with irregularly arrayed ones, we found theoretically that the IAWGs have arbitrary free spectral ranges and are suitable to provide a large number of channels with relatively smaller circuit regions.
