Check out our superstructure grating work!

Our recent superstructure grating work just published in Applied Physics Letters! We demonstrated multiple coherent emission modes at different combinations of frequency and angle, controlled by the superstructure design. These superstructure gratings can be used to tailor the thermal emission of polaritonic thermal emitters. We also suggest the coherence length can be used as an appropriate limit to the periodicity or the total size of a coherent structure for inverse design. Check it out here!
