We demonstrate enhanced photoluminescence from monolayer MoS2 and WS2 by a factor of 60 over the entire emission range using a photonic hypercrystal having hyperbolic dispersion.
We demonstrate an active quantum-dot-embedded two-dimensional photonic hypercrystal that shows 20× enhancement in spontaneous emission rate due to the hyperbolic dispersion and 100× enhancement in light out-coupling due to the photonic-crystal component.
We demonstrate enhanced light extraction and directional emission from a hyperbolic metamaterial embedded with quantum dots. A germanium bull's eye grating is used to enhance the light extraction by a factor of ten.
We report the observation of an optical topological transition in the iso-frequency surface of a non-magnetic anisotropic metamaterial. Enhancement in the photon density of states is demonstrated as a result of this transition.
We demonstrate a topological transition in the iso-frequency surface of a strongly anisotropic metamaterial and show the potential of this optical topological transition for controlling light-matter interaction.
In this paper comprehensive experimental research on high-power semiconductor lasers that possess a non-zero TM-mode power (typically few percent of the total power) and elliptical polarization in solitary configuration in the vicinity of critical angle is described. Critical angle is obtained when the TE(TM)-mode mean power reaches its minimum (maximum). The elliptical polarization of the laser at...
