We present an active physical implementation of the recently introducedplasmon injection loss compensation scheme for Pendry's non-ideal negativeindex flat lens in the presence of realistic material losses andsignal-dependent noise. In this active implementation, we propose to use aphysically convolved external auxiliary source for signal amplification andsuppression of the noise in the imaging system. In comparison with the previouspassive implementations of the plasmon injection scheme for sub-diffractionlimited imaging, where an inverse filter post-processing is used, the activeimplementation proposed here allows for deeper subwavelength imaging far beyondthe passive post-processing scheme by extending the loss compensation to evenhigher spatial frequencies.
