Efficient optical classical and quantum information processing imposes on
light novel requirements: chirality with low threshold non-linearities. In this
work we demonstrate a chiral lasing from an optical modes due to emerging
photonic Rashba-Dresselhaus spin-orbit coupling (SOC). For this purpose we
developed a new electrically tunable device based on an optical cavity filled
with birefringent liquid crystal (LC) and perovskite crystals. Our novel method
for the growth of single crystals of CsPbBr3 inorganic perovskite in polymer
templates allows us to reach a strong light-matter coupling regime between
perovskite excitons and cavity modes, and induce polariton condensation. The
sensitivity of the LC to external electric fields lets us to tune the
condensate energy in situ and induce synthetic SOC. This shapes the condensate
between a single linearly polarized or two circularly polarized separated in
momentum, emitting coherent light. The difference in the condensation
thresholds between the two SOC regimes can be used to switch on and off the
chiral condensate emission with a voltage.Comment: 8 pages, 5 figure
