The proposed optical code-division multiple access(OCDMA) add-drop multiplexer(ADM) is based on arrayed waveguide gratings(AWG) and 2-D time-wavelength code.It drops several code channels simultaneously without disturbing the remaining code channels.The proposed ADM can also add several code channels simulataneously.Furthermore,with using the specific code,such as Prime/OOC,and a small number of AWGs,it is achieved to encode many users simultaneously to make the system compact.Simulation results show the proposed ADM possesses the required functions,according to the success of drop/add two from the 4-user network simultaneously.
