Maximized vertical photoluminescence from optical material with losses employing resonant excitation and extraction of photonic crystal modes

Popis výsledku v původním jazyce

Optical losses of a host material together with the total internal reflection phenomenon can significantly reduce photoluminescence external quantum efficiency of embedded light-emitters. This is not only the case for light emitting color centers in thin layers of nanocrystalline diamond, but also for Si nanocrystals in SiO2 matrices and for some types of perovskite materials. Here, we show that a significant boost (more than 100-fold enhancement) of the directional light emission efficiency from light-emitters in diamond can be achieved by using 2D photonic crystal slabs to extract the light emission into vertical direction (resonant extraction) and at the same time to couple the excitation beam into the structure. We have further shown that this so-called resonant extraction and excitation scheme provides the highest enhancement when the overlap between the electric field distribution of extraction leaky mode and the region of the excited light-emitters is maximized.n
