Achieving energy propagation beyond tens of micrometers is possible with hybrid plasmonic systems. Long-range optical energy propagation (around 600 µm) was demonstrated via photonic modes engineered by the strong coupling of excitons in compact semiconductor dot layers with surface lattice resonances in metal nanoparticle arrays.
Significance and Impact
Results from this research have potential applications in optoelectronics, sensing and quantum information science.
- Photoluminescence measurements and theoretical calculations demonstrated long-range energy propagation generated by the hybrid nanophotonic device shown in the image.
- The visible and near-infrared microscope at the Center for Nanoscale Materials (CNM) was used.
Work was performed in part at CNM.
About Argonne’s Center for Nanoscale Materials
The Center for Nanoscale Materials is one of the five DOE Nanoscale Science Research Centers, premier national user facilities for interdisciplinary research at the nanoscale supported by the DOE Office of Science. Together the NSRCs comprise a suite of complementary facilities that provide researchers with state-of-the-art capabilities to fabricate, process, characterize and model nanoscale materials, and constitute the largest infrastructure investment of the National Nanotechnology Initiative. The NSRCs are located at DOE’s Argonne, Brookhaven, Lawrence Berkeley, Oak Ridge, Sandia and Los Alamos National Laboratories.
