We report a resonant enhancement of luminescence intensity from an ensemble of CdSe/ZnS quantum dots embedded in a nanoscale rectangular photonic waveguide operating in the cutoff regime and therefore experimentally demonstrate the recently predicted phenomenon of increase in the emission rate of an...
