Abstract
Optical add-drop multiplexers will play an important role in enabling greater connectivity and flexibility in dense wavelength-division multiplexing (DWDM) networks. In this paper, a reconfigurable optical add-drop multiplexer (OADM) architecture using a single multiport optical circulator (MOC) and several narrow band fiber Bragg gratings (FBGs) is proposed and demonstrated. The proposed OADM exhibits a lower insertion loss and lower through loss than existing OADMs. The proposed OADM may find important applications in DWDM systems and networks.
