We developed a new arrayed-waveguide-grating (AWG) layout eliminating phase errors and reducing chip size by over 50% for high-order devices. Experimental results show high resolution and low losses, making it ideal for optical applications.

Area of Science:

  • Photonics
  • Integrated optics
  • Waveguide devices

Background:

  • Conventional arrayed-waveguide-grating (AWG) designs suffer from systematic phase errors due to differing bend radii.
  • These errors limit the performance and scalability of AWG devices, particularly for high diffraction orders.
  • Existing designs occupy significant space on semiconductor wafers.

Purpose of the Study:

  • To introduce a novel AWG layout that eliminates systematic phase errors.
  • To reduce the physical footprint of high-order AWG devices.
  • To experimentally validate the performance of the improved AWG design.

Main Methods:

  • Development of an AWG layout featuring identical bends across the entire array.
  • Fabrication of a low-order AWG device utilizing the novel geometry.

  • Experimental characterization of the fabricated device's resolution, insertion loss, and polarization sensitivity.

    • Main Results:

    • The new layout completely eliminates systematic phase errors inherent in conventional designs.
    • A >50% reduction in occupied wafer area was achieved for high-order AWGs.
    • The characterized low-order device demonstrated 5.5 nm resolution, < 2 dB intrinsic losses, and polarization insensitivity over a 215 nm spectral range.

    Conclusions:

    • The improved AWG layout offers significant advantages in performance and size reduction.
    • This design overcomes key limitations of traditional AWG architectures.
    • The experimental validation confirms the practical viability and superior performance of the novel AWG geometry for photonic applications.
