Experimental realization of the active convolved illumination imaging technique for enhanced signal-to-noise ratio
Wyatt Adams, Anindya Ghoshroy, Durdu O. Guney
Imaging is indispensable for nearly every field of science, engineering, technology, and medicine. However, measurement noise and stochastic distortions pose fundamental limits to…
Theory of coherent active convolved illumination for superresolution enhancement
Anindya Ghoshroy, Wyatt Adams, Durdu O. Guney
Recently an optical amplification process called the plasmon injection scheme was introduced as an effective solution to overcoming losses in metamaterials. Implementations with ne…
Plasmonic Superlens Imaging Enhanced by Incoherent Active Convolved Illumination
Wyatt Adams, Anindya Ghoshroy, Durdu Ö. Güney
We introduce a loss compensation method to increase the resolution of near-field imaging with a plasmonic superlens that relies on the convolution of a high spatial frequency passb…
Enhanced superlens imaging with loss-compensating hyperbolic near-field spatial filter
Anindya Ghoshroy, Wyatt Adams, Xu Zhang +1
Recently a coherent optical process called plasmon injection () scheme, which employs an auxiliary source, has been introduced as a new technique to compensate losses in metamat…
Hyperbolic metamaterial as a tunable near-field spatial filter for the implementation of the active plasmon injection loss compensation scheme
Anindya Ghoshroy, Xu Zhang, Wyatt Adams +1
We present how to physically realize the auxiliary source described in the recently introduced active plasmon injection loss compensation scheme for enhanced near-field superlensin…
Active plasmon injection scheme for subdiffraction imaging with imperfect negative index flat lens
Anindya Ghoshroy, Wyatt Adams, Xu Zhang +1
We present an active physical implementation of the recently introduced plasmon injection loss compensation scheme for Pendry's non-ideal negative index flat lens in the presence o…
Perfect compensation of absorption in metamaterials for diffraction-unlimited imaging
Wyatt Adams, Durdu Ö. Güney
To overcome the resolution limit of conventional optics, near field imaging techniques using a negative index flat lens (NIFL) have been previously developed that amplify the evane…
Enhancing the resolution of hyperlens by the compensation of losses without gain media
Xu Zhang, Wyatt Adams, Mehdi Sadatgol +1
We present a method to improve the resolution of available hyperlenses in the literature. In this method, we combine the operation of hyperlens with the recently proposed plasmon i…
Bringing the 'perfect lens' into focus by near-perfect compensation of losses without gain media
Wyatt Adams, Mehdi Sadatgol, Xu Zhang +1
In this paper, the optical properties and imaging performance of a non-ideal Pendry's negative index flat lens with a practical value for loss are studied. Analytical calculations…
