Abstract

We create an optically imprinted gain-trapped polariton wire with a length of 15 μm and a width of 2μm by modulating the shape of a non-resonant excitation spot using a high-resolution spatial light modulator (SLM). We study the spatially, spectrally and temporally resolved emission from the wire and find that the system passes several regimes, starting with an intense emission peak originating from the wire center and develops towards longer living emission from its side. The temporal development of the emission wavelengths corresponding to these peaks allow us to characterize these different emission regimes in terms of photon lasing and polariton condensation.
