Abstract
A phase-conjugated signal is shown theoretically to be induced and enhanced by weak localization of excitonic polaritons in a crystal containing a high density of elastic scatterers under irradiation of a single pump and test beams which are nearly two-photon resonant to a biexciton. This signal is nonexistent without this weak localization so that its observation gives us its direct evidence. Several characteristics peculiar to the weak localization are listed to confirm it. © 1996 The American Physical Society.
