Micro-cavities formed by local defects within an otherwise perfect photonic crystal can trap light and resonate at wave-lengths within the stop-band of the background crystal. An array of equally spaced identical micro-cavities forms the Coupled Cavity Waveguide (CCW) - a narrow band waveguide whose central frequency and bandwidth are determined by the micro-cavities form and their inter-spacing. Such devices can be used as optical or millimeter wave filters, routers, and (de-)multiplexers. In this work we develop a method for matching these devices to external structures. We formulate an optimization problem in which one seeks for the minimum of a properly defined Standing Wave Ratio (SWR), with respect to limited variations of the dielectric structure in the neighborhood of the interface between the sub-system (micro-cavity, CCW) and the external structure. A novel numerical approach to solve this problem is developed and tested on few examples.
