Paper Abstract

Reconfigurable optical add/drop multiplexer (ROADM) is a next generation critical component that facilitates the network system evolution from a point-to-point transmission-oriented structure to an all-optical, wavelength-flexible, dynamic network. ROADM enables flexible removal and insertion of WDM channels at either a head-end or intermediate nodes-making it possible for true network provisioning and reconfiguration. We will review the pros and cons of each of the techniques for tunable OADM, from their operating principles to their practical implementations with special emphasis on two approaches: a TTF based three-port tunable filter as a basic one-channel tunable add/drop multipexer and a full-scale, MEMS mirror array based 80-channel reconfigurable OADM subsystem. Comparative laboratory experimental results with theoretical calculations are presented.
