Enhanced spontaneous emission in photonic hypercrystals
Tal Galfsky, Evgenii E. Narimanov, Vinod M. Menon
We demonstrate a two-dimensional photonic hypercrystal that shows enhanced spontaneous emission from its metamaterial component and light extraction through its photonic crystal pr…
Nonreciprocity and One-Way Topological Transitions in Hyperbolic Metamaterials
Alex Leviyev, Binyamin Stein, Tal Galfsky +4
Control of the electromagnetic waves in nano-scale structured materials is central to the development of next generation photonic circuits and devices. In this context, hyperbolic…
Strong light-matter coupling in two-dimensional atomic crystals
Xiaoze Liu, Tal Galfsky, Zheng Sun +5
Two dimensional (2D) atomic crystals of graphene, and transition metal dichalcogenides have emerged as a class of materials that show strong light-matter interaction. This interact…
Directional out-coupling from active hyperbolic metamaterials
Tal Galfsky, Harish N. S. Krishnamoorthy, Ward D. Newman +3
Hyperbolic Metamaterials (HMMs) have recently garnered much attention because they possess the ability for broadband manipulation of the photon density of states and sub-wavelength…
A giant controllable gap in the optical spectrum of a semiconductor laser subject to intense feedback with rotated polarization
Noam Gross, Zav Shotan, Tal Galfsky +1
A semiconductor laser subject to delayed optical feedback is investigated in the limit of extremely intense feedback power. In a range of feedback polarization rotation angles the…
