Abstract Many bosons can occupy a single quantum state without limit. It is described by the quantum-mechanical Bose–Einstein statistic, which allows condensation at low temperatures and high particle densities. Photons, historically first considered bosonic gas, were late to show this phenomenon, observed in rhodamine-filled microcavities doped fibre cavities. These findings have raised question of whether also common other laser systems with potential technological applications. Here we...
The common understanding of laser operation is based on the non-equilibrium balance between optical gain and losses device, resulting in stimulated emission light above critical pumping threshold. In this contribution, we demonstrate that a broad-area VCSEL can operate state close to thermal equilibrium, enabling Bose-Einstein condensation photons. We observe fundamental mode 23 µm-diameter followed by thermalised distribution photons higher-order modes. Moreover, extracted experimentally...
