Fractional Dimensional Approach to Dielectric Tuning Effects on Excitonic Parameters in 2D semiconductor materials
Lakshminarayan Sharma, Carlos Rodriguez-Fernandez, Humeyra Caglayan
We demonstrated the potential of the fractional dimensional approach to understand exciton parameters in the exemplary atomically thin semiconductor material, a monolayer of WS…
Ultrafast optical properties of stoichiometric and non-stoichiometric refractory metal nitrides TiNx, ZrNx, and HfNx
Jaroslaw Judek, Rakesh Dhama, Alessandro Pianelli +4
Refractory metal nitrides have recently gained attention in various fields of modern photonics due to their cheap and robust production technology, silicon-technology compatibility…
New horizons in near-zero refractive index photonics and hyperbolic metamaterials
Michaël Lobet, Nathaniel Kinsey, Iñigo Liberal +7
The engineering of the spatial and temporal properties of both the electric permittivity and the refractive index of materials is at the core of photonics. When vanishing to zero,…
Two-color all-optical switching in Si-compatible epsilon-near-zero hyperbolic metamaterials
Alessandro Pianelli, Rakesh Dhama, Jaroslaw Judek +2
All-optical ultrafast switches enabled by artificial materials are considered at the forefront of the next generation of photonic communications and data processing. During the las…
Dual-Band Metal-Insulator-Metasurface Absorber
Ibrahim Issah, Carlos Rodríguez Fernández, Mohsin Habib +2
We explored a metal-insulator-metasurface structure exhibiting dual-band absorption in the visible and infrared regions with almost perfect absorbance. We demonstrated that the exi…
Hot electron dynamics and relaxation in hyperbolic meta-antennas
Rakesh Dhama, Mohsin Habib, Alireza R. Rashed +1
Conventional plasmonic nanoantennas enable scattering and absorption bands at the same wavelength region, making their utilization to full potential impossible for both features si…
