| Description | We have developed a method in order to strongly sculpt light fields on the sub-wavelength scale with dielectric nanoantennas. This could enable new forms of single-photon sources for quantum communications. Particular promise is the coupling of these antennas to low-dimensional materials. As a particular promising outcome, we have demonstrated that dielectrictic nanoantennas based on gallium phosphide show significant potential to enhance light emission from two-dimensional materials, published in two articles in Nature Communications and ACS Photonics. Dielectric nanoantennas compare favourably in this regard with their plasmonic, metallic counterparts. We regard this as a key finding going forward in terms of utilizing dielectric nanoantennas as a means to develop quantum light sources based on low-dimensional photon emitters. |
