Wavelength Division Multiplexing (WDM) and Demultiplexing (WDDM) devices are considered to be one of the key elements in optical networks. WDM device by using conventional, such as thin film filter and AWG based devices can only be used as one device either multiplexing or demultiplexing. This paper proposes a novel structure for WDM device, ehic is based on free-space diffraction-grating multiplexer/demultiplexer technology. By using multi-deck fiber arrays one device can function as both multiplexers and demultiplexers simultaneously. This paper will give the structure and working principle for such device. It will also discuss the optical design issues.
