This paper extends the existing theory of two-carrier photorefractivity resonance, which is
generally applied to iron doped indium phosphide (InP: Fe), to the case of low nonharmonic …

We present a new model, which incorporates both temperature and electron–hole effects, for
two-beam coupling in photorefractive semiconductors under an external dc field E_0. We …

We present a new model (including both temperature and electron‐hole effects) of two‐
beam coupling in photorefractive semiconductors under an external dc field E 0. This model …

The theory for two-wave mixing in photorefractive InP: Fe under a dc electric field with both
electron–hole intrinsic resonance and a moving grating is developed. An extended …

A finite difference method is used to analyze the behavior of photorefractive InP: Fe at high
fringe contrast under externally apphed field. The evolution with increasing fringe contrast m …

At wavelengths close to the band edge, strong photorefractive gratings using the Franz–
Keldysh electrorefractive effect can be written in semiconductors. Two‐beam‐coupling …

Photorefractive materials have been assuming ever increasing prominence in the non-linear
optics field due to their unique capability for displaying strong non-linear effects at milliwatt …

We have determined that the dynamics of the signal in photorefractive two beam coupling
can be described by a memory effect in the writing of the space charge field. Experimental …

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 …

We report photorefractive two beam coupling gain coefficients as high as Γ= 19 cm− 1 and
net gains of Γ‐α= 14 cm− 1 in InP: Fe at around 970 nm. This enhancement was achieved by …
