A new paper

I just had a paper, "Photon sorting in the near field using subwavelength cavity arrays in the near-infrared" (based on some of my dissertation work, and lots more excellent work by Isroel Mandel and others) accepted for publication in Applied Physics Letters. The paper is open access, which means the full-text PDF version is available for free.

The idea behind this paper is similar to one we published last year. This structure that we designed and made:

can spectrally and spatially split incoming radiation into different holes in the metal:

Unlike the previous structure, where the incident energy is almost entirely absorbed, this one transmits the light through. Additionally, the other one worked at microwave wavelengths; this device operates at near-IR wavelengths, which is much harder to pull off.

For the rest of the info, read the paper!
