Radiative control of localized excitons at room temperature with an ultracompact tip-enhanced plasmonic nano-cavity
Hyeongwoo Lee, Inki Kim, Chulho Park +7
In atomically thin semiconductors, localized exciton (X) coupled to light shows single quantum emitting behaviors through radiative relaxation processes providing a new class o…
Biomimetic Ultra-Broadband Perfect Absorbers Optimised with Reinforcement Learning
Trevon Badloe, Inki Kim, Junsuk Rho
By learning the optimal policy with a double deep Q-learning network, we design ultra-broadband, biomimetic, perfect absorbers with various materials, based the structure of a moth…
Tungsten based metasurface absorber for visible regime
Ahsan Sarwar Rana
Utilizing solar energy requires perfect absorption by photovoltaic cells for efficient conversion of solar energy into useful electrical energy. Metasurfaces can, not only be used…
Nanophotonic modal dichroism: mode-multiplexed modulators
Susobhan Das, Shima Fardad, Inki Kim +3
As the diffraction limit is approached, device miniaturization to integrate more functionality per area becomes more and more challenging. Here we propose a novel strategy to incre…
A highly efficient method for second and third harmonic generation from magnetic metamaterials
Iman Sajedian, Inki Kim, Abdolnasser Zakery +1
Second and third harmonic signals have been usually generated by using nonlinear crystals, but that method suffers from the low efficiency in small thicknesses. Metamaterials can b…
The role of current loop in harmonic generation from magnetic metamaterials in two polarizations
Iman Sajedian, Inki Kim, Abdolnasser Zakery +1
In this paper, we investigate the role of the current loop in the generation of second and third harmonic signals from magnetic metamaterials. We will show that the fact that the c…
