Signatures of the excitonic-polaritonic condensates affected by thermal fluctuations in an electron-hole mass imbalance optical microcavity are inspected. In the framework of the unrestricted Hartree-Fock approximation, a two-band electronic model with mater-light coupling is solved and we find a set of self-consistent equations specifying the excitonic and photonic condensate order parameters. Numerical results reveal a complex competition between the instabilities of the excitonic, polaritonic and photonic condensation states under the influence of the electron-hole mass imbalance and the thermal fluctuations. The distinctive features of excitonic-polaritonic-photonic condensates are also characterized by the momentum distributions of the electron-hole pair amplitude and the photonic density.
