We experimentally demonstrate long range (∼160 nm) energy transfer in a donor-acceptor pair across a metamaterial designed such that the epsilon-near-zero regime coincided with the donor emission.
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 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.
Control of spontaneous emission, which is one of the fundamental concepts in the field of quantum optics, has been reported using photonic crystals and microcavities through the Purcell effect. Increasing the photonic density of states (PDOS) is the key to enhancing the spontaneous emission from emitters which have a low quantum yield. There have been several reports on the enhancement of spontaneous...
In this paper photonic devices incorporating colloidal quantum dots are demonstrated. One-dimensional microcavity structure are fabricated using a combination of low temperature plasma enhanced chemical vapor deposition and spin coating. Enhancement in spontaneous emission from the CdSe/ZnS core/shell QDs embedded in the microcavity is demonstrated through steady state and time resolved luminescence...
Here we report the observation of Bloch-polaritons in a GaAs/AlGaAs multiple-quantum-well structure. We observe three polariton states formed by the coherent interaction between light- and heavy-hole excitonic-lattices, and Bloch waves of the background photonic crystal.
