Orientational dependence of photorefractive two-beam coupling in InP:Fe.
We present the theory for photorefractive two-beam coupling without optical activity in cubic crystals rotated around the [110] axis. We also describe two-beam coupling experiments in InP:Fe that fit the theory closely. The 15.5% gain enhancement for grating wave vectors aligned along the <111> directions is demonstrated explicitly.
