New work by V. Janonis et al. is published in Optics Express

Most recent study by V. Janonis and co-authors “Spatial coherence of hybrid surface plasmon-phonon-polaritons in shallow n-GaN surface-relief gratings” is published in the highly ranked Optics Express journal from Optical Society of America (OSA) Publishing. Good agreement was achieved between experiment and theory paving a way for development of narrow-band thermal sources of coherent radiation in IR and THz ranges. The work was funded by the European Regional Development Fund according to the supported activity “Research Projects Implemented by World-class Researcher Groups” under the Measure No. 01.2.2-LMT-K-718-0047 through the Research Council of Lithuania (Lietuvos mokslo taryba) grant the “KOTERA-PLAZA” Project (No. DOTSUT-247).  Note, that this publication is Open Access and can be reached through this link:
