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.
利用Franz-Keldysh效应研究III-V类化合物光折变增益的可能的高效Pockels效应。
由于III-V型半导体具有较低的电光系数,因此有望在无外场的双波混频(2WM)等实验中获得较好的光折变性能。然而,我们最近通过实验和理论表明,InP:Fe的平均增益高于10 cm-1(与理论一致,最大值为20 cm-1)[1,2]。该增益足够高,可以在1.06 μm处获得双相共轭镜(DPCM)现象,样品长度不超过5 mm[2]。这种高增益的潜在物理是空穴和电子发射的协同作用,产生了一种新的共振机制[1],这里将其命名为流体动力共振。
