Cavity polaritons are quasiparticles arising from the strong coupling between light and matter. By using organic dyes with large exciton binding energies as the active layer, polaritons can be generated even at room temperature, making them promising for next-generation optical-device applications. Most previous studies on organic cavity polaritons have focused on the visible region, whereas realization in the longer-wavelength near-infrared to infrared region is desirable from the standpoint of telecommunications and bio-applications. In this work, we fabricated a microcavity employing an infrared-emitting BF2-complex dye together with a liquid crystal as the active layer, and observed low-threshold lasing in the near-infrared region that is attributed to polaritons. We report these results here.
