Ultrafast optical control of polariton energy in an organic semiconductor microcavity
Kirsty E. McGhee, Michele Guizzardi, Rahul Jayaprakash +8
The manipulation of exciton-polaritons and their condensates is of great interest due to their applications in polariton simulators and high-speed, all-optical logic devices. Until…
Nonlinear interactions of dipolar excitons and polaritons in MoS2 bilayers
Charalambos Louca, Armando Genco, Salvatore Chiavazzo +12
Nonlinear interactions between excitons strongly coupled to light are key for accessing quantum many-body phenomena in polariton systems. Atomically-thin two-dimensional semiconduc…
Tuning the coherent propagation of organic exciton-polaritons through dark state delocalization
Raj Pandya, Arjun Ashoka, Kyriacos Georgiou +7
While there have been numerous reports of long-range polariton transport at room-temperature in organic cavities, the spatio-temporal evolution of the propagation is scarcely repor…
Untargeted Effects in Organic Exciton-Polariton Transient Spectroscopy: A Cautionary Tale
Scott Renken, Raj Pandya, Kyriacos Georgiou +6
Strong light-matter coupling to form exciton- and vibropolaritons is increasingly touted as a powerful tool to alter the fundamental properties of organic materials. It is proposed…
Strong Exciton-Photon Coupling in Large Area MoSe and WSe Heterostructures Fabricated from Two-Dimensional Materials Grown by Chemical Vapor Deposition
Daniel J. Gillard, Armando Genco, Seongjoon Ahn +11
Two-dimensional semiconducting transition metal dichalcogenides embedded in optical microcavities in the strong exciton-photon coupling regime may lead to promising applications in…
Ultrafast long-range energy transport via light-matter coupling in organic semiconductor films
Raj Pandya, Richard Y. S. Chen, Qifei Gu +29
The formation of exciton-polaritons allows the transport of energy over hundreds of nanometres at velocities up to 10^6 m s^-1 in organic semiconductors films in the absence of ext…
Generation of Anti-Stokes Fluorescence in a Strongly Coupled Organic Semiconductor Microcavity
Kyriacos Georgiou, Rahul Jayaprakash, Alexis Askitopoulos +3
We explore the generation of anti-Stokes fluorescence from strongly coupled organic dye microcavities following resonant ground-state excitation. We observe polariton emission alon…
Extraction of absorption coefficients from GaN nanowires grown on opaque substrates
Rahul Jayaprakash, Debo Ajagunna, Savvas Germanis +4
We demonstrate a new method to measure absorption coefficients in any family of nanowires, provided they are grown on a substrate having considerable difference in permittivity wit…
