Abstract

We present what we believe to be the first experimental measurements of magneto-optic phase conjugation observed in degenerate four-wave mixing in Cd_0.9Mn_0.1Te. The experiments are performed in the longitudinal Faraday geometry¹ with the transmission grating vector oriented along [1T1] and the magnetic field applied along [110]. The experimental results as a function of applied magnetic field and incident wave polarization agree well with coupled-mode theory, The magnetic field removes time-reversal symmetry and quenches orthogonal components of the phase-conjugate signal for selected field strengths. This mixing geometry is equivalent to a phase conjugate mirror with a built-in Faraday isolator.
