We developed a compact Mach-Zehnder interferometer (MZI)-synchronized arrayed-waveguide grating (AWG) multiplexer. This device offers low insertion loss and a flat-top response for 40 optical channels.

Area of Science:

  • Photonics and Optical Engineering
  • Integrated Optics
  • Telecommunications

Background:

  • Arrayed-waveguide gratings (AWGs) are crucial for wavelength division multiplexing (WDM) in optical networks.
  • Miniaturization and improved performance of AWG devices are essential for next-generation optical systems.
  • Mach-Zehnder interferometer (MZI) synchronization offers potential benefits for AWG performance.

Purpose of the Study:

  • To develop a compact and high-performance MZI-synchronized AWG multiplexer.
  • To achieve low insertion loss and a flat-top frequency response in a miniaturized device.
  • To demonstrate the effectiveness of specific design techniques for AWG optimization.

Main Methods:

  • Design and fabrication of a compact MZI-synchronized AWG using 1.5-% Delta waveguides.

  • Integration of spot-size converters at input/output waveguides to reduce coupling loss.
  • Implementation of a narrow gap in a directional coupler at the MZI-AWG junction to minimize losses.
  • Characterization of the device for insertion loss, frequency response, passband, and crosstalk.

    • Main Results:

    • A compact MZI-synchronized AWG multiplexer with 40 channels spaced at 100 GHz was successfully developed.
    • The device achieved a small chip size of 35 x 28 mm(2).
    • Low insertion loss (1.0 - 1.2 dB) and a flat-top frequency response were obtained.
    • Excellent performance metrics include a wide 0.5-dB passband (>45 GHz) and low adjacent crosstalk (< -35 dB).

    Conclusions:

    • The developed MZI-synchronized AWG represents a significant advancement in compact multiplexer technology.
    • The design strategies employed effectively reduced insertion loss and improved spectral characteristics.
    • This compact and high-performance device is suitable for advanced WDM systems requiring miniaturization and efficiency.
