  • reception of mode division multiplexed superchannel via few mode compatible optical add drop multiplexer
    Optics Express, 2012
    Co-Authors: Xi Chen, Abdullah Al Amin, William Shieh
    Abstract:

    We report the first few-mode compatible optical add/drop multiplexer (OADM) that enables add/drop functionality for mode division multiplexed (MDM) superchannels. The OADM is comprised of two cascaded free-space thin-film filters with 5° incident angle. The transmission of MDM superchannel CO-OFDM signals via the OADM is investigated. The experimental result shows that the OSNR penalties for add, drop and through ports are 2.6, 2.4, 0.7 dB, respectively for 3x318 Gb/s superchannels.

  • first inp based reconfigurable integrated add drop multiplexer
    IEEE Photonics Technology Letters, 1997
    Co-Authors: Cgm Vreeburg, T. Uitterdijk, Ys Oei, Fh Groen, M K Smit, E G Metaal, P Demeester, H. J. Frankena
    Abstract:

    A four-channel reconfigurable integrated add-drop multiplexer on InP-substrate is reported. The device consists of a 5/spl times/5 PHASAR demultiplexer integrated with Mach-Zehnder interferometer electrooptical switches. Total device size is 3/spl times/6 mm/sup 2/. All routing configurations of four wavelengths have been demonstrated. Crosstalk values are better than -20 dB. On-chip loss for the dropped or added signals and for the signals coupled from the input to the output port are lower than 7 and 11 dB, respectively.

  • Compact integrated InP-based add-drop multiplexer

    Co-Authors: Cgm Vreeburg, T. Uitterdijk, Ys Oei, Mk Meint Smit, Fh Groen, J.j.g.m. Van Der Tol, P. Domeester, H. J. Frankena
    Abstract:

    A 4-channel integrated add-drop multiplexer on InP-substrate is realised. Total on chip-loss is less than 10.7 dB for the pass-function and less than 6.7 dB for both the add and drop function. Crosstalk values are lower than -20 dB.

  • Remote provisioning of a reconfigurable WDM multichannel add/drop multiplexer
    IEEE Photonics Technology Letters, 1999
    Co-Authors: Roberto Gaudino, Daniel J. Blumenthal
    Abstract:

    Remote provisioning of a nonblocking reconfigurable multichannel wavelength-division-multiplexed add-drop multiplexer (ADM) is experimentally demonstrated. The ADM add/drop multiplexer supports many features required by the ITU optical channel layer including lightpath routing, signal conditioning and network/channel monitoring. Specifically, the node supports multichannel optical bypass and add/drop functions as well as optoelectronic 2R regeneration and channel drop-and-continue with wavelength translation. Provisioning of a slave node from a remote master node is achieved via a subcarrier encoded control channel. The control channel can set the full state of the ADM and demonstration of switching between two states is reported. A reconfiguration time of the order of 10 /spl mu/s and BER below 10/sup -9/ are shown in both configurations. This performance meets the requirements of next-generation reconfigurable/restorable optical networks.

  • Acousto optic devices in add/drop multiplexer nodes
    24th European Conference on Optical Communication. ECOC '98 (IEEE Cat. No.98TH8398), 1
    Co-Authors: F. Arecco, Daniel J. Blumenthal, D. Scarano, S. Schmid, Roberto Gaudino
    Abstract:

    Two advanced network demonstrators with optical add drop multiplexing (OADM) nodes integrating acousto optic devices are presented. Based on the obtained results, a new generation of acousto optic add/drop multiplexers for dense WDM networks has been developed. We present the latest fundamental progress in the development of acousto optic devices, based on the results obtained from the OADM nodes in the Italian PROMETEO field trial and the MOSAIC experimental network testbed.
