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…
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…
Hyperbolic Metamaterial Feasible for Fabrication with Direct Laser Writing Processes
Xu Zhang, Sanjoy Debnath, Durdu Ö. Güney
Stimulated emission depletion microscopy inspired direct laser writing (STED-DLW) processes can offer diffraction-unlimited fabrication of 3D-structures, not possible with traditio…
Birefringence of Muscovite Mica Plate Temperature Effect in the Ultraviolet and Visible Spectrum
Xu Zhang, Fuquan Wu, Limei Qi +2
We developed a method to measure the phase retardation and birefringence of muscovite mica plate in the temperature range of 223K to 358K within the spectrum of 300 to 700 nm. The…
