  • Spectral phase encoded time spread optical code division multiple access technology for next generation communication networks Invited
  • 2007
  • In: Journal of Optical Networking. - 1536-5379. ; 6:10, s. 1210-1227
  • Journal article (peer-reviewed)abstract
    • We overview and summarize the progress of the spectral phase encoded time spreading (SPECTS) optical code division multiple access (O-CDMA) technology. Recent progress included a demonstration of a 320 Gbit/s (32-user x 10 Gbit/s) all-optical passive optical network testbed based on the SPECTS O-CDMA technology and a theoretical prediction of the spectral efficiency at 100% and above. In particular, InP-based integrated photonics allows implementation of SPECTS O-CDMA transmitters and receivers monolithically integrated on a chip. The integrated InP chip technology not only allows robust and compact configurations for practical and low-cost O-CDMA network deployments but also offers code reconfigurations at rapid rates for secure communication applications.

  • 10-GHz and 20-GHz channel spacing high-resolution AWGs on InP
  • 2009
  • In: IEEE Photonics Technology Letters. - 1041-1135 .- 1941-0174. ; 21:5, s. 298-300
  • Journal article (peer-reviewed)abstract
    • This letter reports on 10-GHz and 20-GHz channel-spacing arrayed waveguide gratings (AWGs) based on InP technology. The dimensions of the AWGs are 6.8 × 8.2 mm2 and 5.0 × 6.0 mm2, respectively, and the devices show crosstalk levels of 12 dB for the 10-GHz and 17 dB for the 20-GHz AWG without any compensation for the phase errors in the arrayed waveguides. The root-mean-square phase errors for the center arrayed waveguides were characterized by using an optical vector network analyzer, and are 18° for the 10-GHz AWG and 28° for the 10-GHz AWG.

  • Determination of 20 GHz InP AWG phase errors by measurement of AWG pulse train
  • 2007
  • In: 2007 IEEE LEOS Annual Meeting Conference Proceedings. - : IEEE. - 142440925X - 9781424409259 ; , s. 725-726
  • Conference paper (peer-reviewed)abstract
    • The phase errors of a 20 GHz AWG fabricated on InP are determined by measuring the intensity and phase of the pulse train produced by the transmission of a short pulse through an AWG.

  • Heteroepitaxy and selective epitaxy for discrete and integrated devices
  • 2006
  • In: 2006 CONFERENCE ON OPTOELECTRONIC AND MICROELECTRONIC MATERIALS & DEVICES. - NEW YORK : IEEE. - 9781424405770 ; , s. 309-311
  • Conference paper (peer-reviewed)abstract
    • We present first results on heteroepitaxy of InP on silicon on insulator (SOI). We also demonstrate InP nanopillar fabrication by means of selective epitaxy. Selective epitaxy is also exploited to fabricate advanced photonic integrated devices for Optical Code Division Multiplex Access (OCDMA) networking applications.

  • 2007
  • In: 2007 33rd European Conference and Exhibition of Optical Communication, ECOC 2007. - : IEEE conference proceedings. - 9783800730421
  • Conference paper (peer-reviewed)abstract
    • We demonstrate a 10-channel InP-based Arrayed-Waveguide Grating (dimensions = 5.0×6.0 mm2) with a 20-GHz channel spacing. The excess loss of the AWG is 5.5-6.3 dB, and the crosstalk level is below -15 dB.

  • In: 2007 IEEE LEOS annual meeting conference proceedings. - : IEEE. - 142440925X - 9781424409259 ; , s. 723-724
  • Conference paper (peer-reviewed)abstract
    • A very compact InP-Based 16-channel O-CDMA encoder-/decoder chip (3.8mm × 6.8mm) has been designed, fabricated and characterized. The device successfully performs O-CDMA spectral encoding.

  • InP-based arrayed-waveguide grating with a channel spacing of 10 GHz
  • 2008
  • In: OFC/NFOEC - Conf. Opt. Fiber Commun./Natl. Fiber Opt. Eng. Conf.. - 9781557528551 ; , s. -69
  • Conference paper (peer-reviewed)abstract
    • We realize a high-precision 10-channel InP-based Arrayed-Waveguide Grating (AWG) with a 10-GHz channel spacing. The AWG showed approximately 10dB excess-loss, 10 dB crosstalk, and 8.2 × 6.8 mm2 dimensions.
