Compact Contra-Directional-Coupler-Based Filters for CWDM Applications

We experimentally demonstrate and compare contra-directional-coupler-based filters in a compact series cascaded configuration and an ultra-compact, fabrication variation tolerant, parallel stacked configuration. Both filters are shown to be similar in performance as regards their sidelobe suppressio...

Description
Summary:We experimentally demonstrate and compare contra-directional-coupler-based filters in a compact series cascaded configuration and an ultra-compact, fabrication variation tolerant, parallel stacked configuration. Both filters are shown to be similar in performance as regards their sidelobe suppression ratios and bandwidths.
