—A novel wavelength-division-multiplexing add–drop module is proposed using free-space cascaded thin-film filters. The athermal design of the filters creates a natural curvature that is shown to compensate for diffraction and optical misalignment. We demonstrate an insertion loss of 1.1 dB for four cascaded filters.
