Abstract

The dependence of a two-beam coupling gain on the grating period in Fe-doped InP is characterized. I measure gains as large as 4 cm⁻¹ at 1.06 μm for an applied field of 8 kV cm⁻¹ and for a grating period between 3 and 12 μm. Moreover, there is gain saturation above a reference-beam intensity of 40 mW cm⁻² and response times from 1 to 30 msec depending on the applied field.
