Enhanced spontaneous emission in photonic hypercrystals

Autor: Galfsky, Tal, Narimanov, Evgenii E., Menon, Vinod M.

We demonstrate a two-dimensional photonic hypercrystal that shows enhanced spontaneous emission from its metamaterial component and light extraction through its photonic crystal property. Spontaneous decay rate is enhanced by a factor of 19.5 and lig

Nonreciprocity and One-Way Topological Transitions in Hyperbolic Metamaterials

Autor: Leviyev, Alex, Stein, Binyamin, Galfsky, Tal, Krishnamoorthy, Harish, Kuskovsky, Igor L., Menon, Vinod, Khanikaev, Alexander B.

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 metamaterials, where elliptical isofrequency surfaces are morphed into

Strong light-matter coupling in two-dimensional atomic crystals

Autor: Liu, Xiaoze, Galfsky, Tal, Sun, Zheng, Xia, Fengnian, Lin, Erh-chen, Lee, Yi-Hsien, Kéna-Cohen, Stéphane, Menon, Vinod M.

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 interaction can be further controlled by embedding such materials into optical

Directional out-coupling from active hyperbolic metamaterials

Autor: Galfsky, Tal, Krishnamoorthy, Harish N. S., Newman, Ward D., Narimanov, Evgenii, Jacob, Zubin, Menon, Vinod M.

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 light confinement. However, a major difficulty arises with the coupli

Report

A giant controllable gap in the optical spectrum of a semiconductor laser subject to intense feedback with rotated polarization

Autor: Gross, Noam, Shotan, Zav, Galfsky, Tal, Khaykovich, Lev

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 emission spectra of the laser reveal a giant gap with width of more th
