Optics Express Publishes 2nd Annual Special Issue on ECOC 2012 Conference Proceedings

WASHINGTON, Dec. 10, 2012—The Optical Society (OSA) today published a series of papers as part of an upcoming Special Issue on the 2012 European Conference on Optical Communication (ECOC) in its open-access journal Optics Express.  The effort is a continuation of OSA’s existing partnership with ECOC. The issue features in-depth versions of 134 papers from the conference, covering hot topics such as multicore components, hybrid optoelectronic devices, scalable 100 Gb/s transmitters, cooperative coherent receivers and others. 

The issue includes submissions from 37 percent of authors of the 350+ papers presented in Amsterdam, Sept. 16 – 20.  It was organized by the general and program chairs and edited by the subcommittee chairs of ECOC’s technical categories:
General Chairs:

  • Ton Koonen, COBRA – Eindhoven University, The Netherlands
  • Peter van Daele, iMinds – Ghent University, Belgium

Program Chairs:

  • Harm Dorren, COBRA – Eindhoven University, The Netherlands
  • Piet Demeester, iMinds – Ghent University, Belgium

Subcommittee Chairs:

  • Juerg Leuthold, Karlsruhe Institute of Technology, Germany (Waveguide and Optoelectronic Devices)
  • Patrice Megret, University of Mons, Belgium (Fibers, Fiber Devices, and Amplifiers)
  • Mario Pickavet, iMinds – Ghent University,  Belgium (Backbone and Core Networks)
  • Antonio Teixeira, University of Aveiro Portugal, Portugal (Subsystems for Optical Network)
  • Eduward Tangdionnga, COBRA - Eindhoven University, The Netherlands (Access Networks and LAN)
  • Huug de Waardt, COBRA - Eindhoven University, The Netherlands (Transmission Systems and Network Elements)

“Through this partnership with a high-impact peer-reviewed journal like Optics Express, the researchers presenting their work at ECOC were given a unique opportunity to expand upon what was presented in September into a full-length technical manuscript,” said Martijn de Sterke, editor-in-chief of Optics Express. “This is a big win for everyone involved. We’re very pleased to promote this high-quality content in an open access format for the benefit of optical communications researchers and the field as a whole.”

Key Findings and Select Papers

The following papers were identified by the subcommittee chairs as highlights of the Optics Express Special Issue on ECOC 2012. All are included in Volume 20, Issue 26 and can be accessed online at

Paper: “112-Gb/s monolithic PDM-QPSK modulator in silicon,” P. Dong(1),  et al., Optics Express, Vol. 20, Issue 26, pp. B624-B629 (2012). (1)Alcatel-Lucent Bell Labs, USA.

From the chair: This paper shows the impressive progress that the field of integrated optics is undergoing. While 10 years ago silicon photonics was a rather sparse field, it has turned into a dynamic research field with impressive progress that might soon give pace to the industry. The authors demonstrate a fully integrated silicon photonic IQ-modulator pair with a built-in polarization multiplexer. It features ultra-compact dimensions of 1.4 mm x 13 mm and reasonable low on-chip losses of 4.6 dB.

Paper: “Real-time OFDM or Nyquist pulse generation – which performs better with limited resources?” R. Schmogrow(1), et al., Optics Express, Vol. 20, Issue 26, pp. B543-B551 (2012). (1)Karlsruhe Institute of Technology, Germany.

From the chair: Nowadays, much focus is put on resources required for enabling advanced technologies that improve fiber bandwidth usage. In this paper, the authors give an “apples to apples” comparison of the implications and resources required for Orthogonal Frequency-Division Multiplexing (OFDM) and Nyquist single channel and wavelength division multiplexing (WDM) approaches.

Paper:  “Uncoupled multi-core fiber enhancing signal-to-noise ratio,” T. Hayashi(1), et al., Optics Express, Vol. 20, Issue 26, pp. B94-B103 (2012). (1)Sumitomo Electric Industries, Ltd., Japan.

From the chair: This paper addresses the realization of a low-loss multicore fiber (MCF) and presents a record effective area of 120 µm^2 and attenuation of 0.17 dB/km for a 7-core fiber with acceptable cladding and crosstalk values. For the last two decades, the transmission capacity of single-core fibers has increased by more than three orders of magnitude. However, in recent years, these increases have leveled off. In this paper, the authors demonstrate the potential of using an MCF to overcome the capacity limit of single-core fiber transmission systems.
