Beaming Elastic and SERS Emission from Bent-Plasmonic Nanowire on a Mirror Cavity
Sunny Tiwari, Adarsh B. Vasista, Diptabrata Paul +2
We report on the experimental observation of beaming elastic and surface enhanced Raman scattering (SERS) emission from a bent-nanowire on a mirror (B-NWoM) cavity. The system was…
Effect of molecular absorption and vibrational modes in polariton assisted photoemission from a layered molecular material
Adarsh B Vasista, Kishan S Menghrajani, William L Barnes
The way molecules absorb, transfer, and emit light can be modified by coupling them to optical cavities. The extent of the modification is often defined by the cavity-molecule coup…
Differential molecule-cavity mode coupling in soft-cavities
Adarsh B Vasista, William L Barnes
The way molecules absorb, transfer, and emit light can be dramatically modified by coupling them to optical cavities. The extent of the modification is often defined by the cavity-…
Momentum-resolved surface enhanced Raman scattering from a nanowire-nanoparticle junction cavity
Adarsh B. Vasista, Shailendra K. Chaubey, David J. Gosztola +3
Herein we report experimental evidence of directional SERS from molecules situated inside a single nanowire-nanoparticle junction cavity. The emission was confined to a narrow rang…
Observation of photonic spin-momentum locking due to coupling of achiral metamaterials and quantum dots
Ravindra Kumar Yadav, Wenxiao Liu, SRK Chaitanya Indukuri +4
Here, we report observations of photonic spin-momentum locking in the form of directional and chiral emission from achiral quantum dots (QDs) evanescently coupled to achiral hyperb…
Molecular monolayer strong coupling in dielectric soft microcavities
Adarsh B Vasista, William L Barnes
We report strong coupling of a monolayer of J-aggregated dye molecules to the whispering gallery modes of a dielectric microsphere at room temperature. We systematically studied th…
