We study the light-matter coupling of microcavity photon and interband transition in a one-dimensional (1D) nanowire. Due to the Van Hove singularity in the density of states resulting in resonant character of the absorption line the achievement of strong coupling becomes possible even without formation of a bound state of an electron and a hole. The calculated absorption in the system and corresponding energy spectrum reveal anti-crossing behavior characteristic to the formation of polariton modes. Contrary to the case of conventional exciton polaritons, formation of 1D Van Hove polaritons will not be restricted to low temperatures and can be realized in any system with a singularity in the density of states.
