In the last few years photonic metamaterials have experienced incredible gains in subwavelength-scale nanostructures with elaborately designed periodic and disordered photonic materials for applications in integrated photonics. Silicon-on-Sapphire is helping advance subwavelength engineering used in silicon photonic devices.

Researchers are using subwavelength gratings and hyperuniform disordered photonic structures to attain state-of-the-art performances for the near- and mid-infrared applications in:

  • fiber-chip coupling
  • slot waveguides for refractive-index sensing
  • mode conversion
  • wavelength filtering
  • integrated resonators
  • ultracompact high-extinction
  • broadband integrated polarizers.
