Query: Stable Switching among High-Order Modes in Polariton Condensates   We report multistate optical switching among high-order bouncing-ball modes
("ripples") and whispering-gallerying modes ("petals") of exciton-polariton
condensates in a laser-generated annular trap. By tailoring the diameter and
power of the annular trap, the polariton condensate can be switched among
different trapped modes, accompanied by redistribution of spatial densities and
superlinear increase in the emission intensities, implying that polariton
condensates in this geometry could be exploited for a multistate switch. A
model based on non-Hermitian modes of the generalized Gross-Pitaevskii equation
reveals that this mode switching arises from competition between pump-induced
gain and in-plane polariton loss. The parameters for reproducible switching
among trapped modes have been measured experimentally, giving us a phase
diagram for mode switching. Taken together, the experimental result and
theoretical modeling advances our fundamental understanding of the spontaneous
emergence of coherence and move us toward its practical exploitation.
