Abstract

Integrated optical devices based on coupled resonator optical waveguides (CROW) for reconfigurable band routing are explored. A reconfiguration principle based on two bus interferometric CROW resonant structures is proposed. This device extends the functionalities of simple add-drop filters, adding more switching features. These new functionalities yield three functional states that comprehend a complete reconfigurability and a 50% splitter mode.
