Abstract
Modest performance of photorefractive III-V semiconductors is expected in experiments such as two wave mixing (2WM) in the absence of external field, due to their low electro-optic coefficient. Nevertheless we have recently shown experimentally and theoretically that InP:Fe exhibits an average gain higher than 10 cm-1 (with maximum of 20 cm-1 in agreement with theory) [1,2]. This gain can be high enough to obtain the Double Phase Conjugated Mirror (DPCM) phenomena at 1.06 μm with a sample no longer than 5 mm [2]. The underlying physics of such high gain is a synergy of hole and electron emissions giving rise to a new mechanism of resonance [1], which will be named here hydrodynamic resonance.
