Main Results:

  • Fabricated large-area (>0.5 cm2), defect-free gratings with submicrometer features down to 160 nm.
  • Demonstrated increased DE with larger NC diameter (7.3 nm NCs achieved 25-30% DE at 488 nm vs. 15% for 2.5 nm NCs).
  • Correlated DE enhancement with changes in the real (n) and imaginary (k) components of the refractive index.

Conclusions:

  • Facile microcontact molding enables efficient CdSe NC diffraction gratings.
  • NC size is a key parameter for optimizing diffraction efficiency.
  • These gratings offer novel applications for in- and out-coupling laser radiation into optical elements like waveguides.
