Abstract.

We report on double-peak thermally tuned reflectivity of optical phase conjugation in InP:Fe under dc fields. A single-pump four-wave mixing geometry generates a phase-conjugate reflectivity up to 6.7% for a pump intensity of 28 mW/cm2 at 1.32 μm wavelength. The phase-conjugate reflectivity exhibits strong temperature dependence that is attributed to the phase-shift variations of the index grating due to optical power density of the intensity distribution. Two strong peaks in phase-conjugate reflectivity are observed near room temperature and are separated by 3 °C. Our theoretical predictions, which are based on the modified single-defect model, are in good agreement with the experimental findings.
