Journal: | Light: Science & Applications | Abstract: | Exciton-polariton condensation is regarded as a spontaneous macroscopic quantum phenomenon with phase ordering and collective coherence. By engineering artificial annular potential landscapes in halide perovskite semiconductor microcavities, we experimentally and theoretically demonstrate the room-temperature spontaneous formation of a coherent superposition of exciton-polariton orbital states with symmetric petal-shaped patterns in real space, resulting from symmetry breaking due to the anisotropic effective potential of the birefringent perovskite crystals. The lobe numbers of such petal-shaped polariton condensates can be precisely controlled by tuning the annular potential geometry. These petal-shaped condensates form in multiple orbital states, carrying locked alternating π phase shifts and vortex–antivortex superposition cores, arising from the coupling of counterrotating exciton-polaritons in the confined circular waveguide. Our geometrically patterned microcavity exhibits promise for realizing room-temperature topological polaritonic devices and optical polaritonic switches based on periodic annular potentials. | URI: | https://hdl.handle.net/10356/151829 | ISSN: | 2095-5545 | DOI: | 10.1038/s41377-021-00478-w | DOI (Related Dataset): | 10.21979/N9/UNX5DX | Schools: | School of Physical and Mathematical Sciences | Organisations: | MajuLab @ NTU | Research Centres: | CNRS International NTU THALES Research Alliances | Rights: | © 2021 The Author(s).
