Bose Condensation of Upper-Branch Exciton-Polaritons in a Transferable Microcavity
Exciton-polaritons are composite quasiparticles that
result from
the coupling of excitonic transitions and optical modes. They have
been extensively studied because of their quantum phenomena and potential
applications in unconventional coherent light sources and all-optical
control elements. In this work, we report the observation of BoseāEinstein
condensation of the upper polariton branch in a transferable WS2 monolayer microcavity. Near the condensation threshold, we
observe a nonlinear increase in upper polariton intensity accompanied
by a decrease in line width and an increase in temporal coherence,
all of which are hallmarks of BoseāEinstein condensation. Simulations
show that this condensation occurs within a specific particle density
range, depending on the excitonic properties and pumping conditions.
The manifestation of upper polariton condensation unlocks new possibilities
for studying the condensate competition while linking it to practical
realizations in polaritonic lasers. Our findings contribute to the
understanding of bosonic systems and offer potential for the development
of polaritonic devices
