With the super nano-grating, the resonance of the nanostructure can be measured with a photodetector array.

The super nano-grating is a super-period nanohole array drilled in a thin gold film on a transparent glass substrate.

With a fabricated super nano-grating, Dr. Guo's group demonstrated a new kind of optical sensing apparatus called spectrometer sensors.

Dr. Junpeng Guo, Associate Professor of Electrical Engineering and Optics at UAHuntsville, recently created a new nanoscale photonic device called a super nano-grating, with the assistance of his doctoral student, Haisheng Leong.
