Fig. 1: Schematic structure and characterisation of one-dimensional trapping.
From: Optically trapped room temperature polariton condensate in an organic semiconductor
a Experimental scheme with the patterned pump incident on the substrate of a planar microcavity and the emission collected from the cavity surface. The left image shows two neighbouring Gaussian beams forming a 1D potential. The arrows denote the dominant flows of polaritons toward the bottom of the potential. b–e Experimental and f–i theoretical real-space images of condensate emission for two 6.6 μm × 4.5 μm pump spots separated by 4.1 μm (b, f); 5.6 μm (c, g); 8.8 μm (d, h); and 10 μm (e, i). White dashed ellipses indicate the pump spots. j–m Corresponding experimental and n–q theoretical real-space spectra along the centre of real-space images indicated by the dashed line in (b).
