Abstract

We demonstrated for what is the first time to our knowledge photorefractive two-wave mixing in a bulk ferroelectric crystal using cw light at the telecommunication wavelength 1.55 μ m . In the Te-doped ferroelectric semiconductor Sn 2 P 2 S 6 with absorption constant < 0.1 cm 1 at 1.55 μ m , grating recording times of 10 ms and a two-beam coupling gain of 2.8 cm 1 have been measured at 350 mW power (intensity 440 W cm 2 ) without a necessity to apply an external electric field. With a moving grating technique, a maximal gain of 6.0 cm 1 has been obtained.
