我们报道了在非晶半导体玻璃中观测到的一种类光折变非线性效应，这种非线性效应是导致巨浮雕调制形成的原因。基质的光致软化，形成具有增强的极化率的缺陷，以及它们在光场梯度力下的漂移被认为是质量输运的起源。
We report the observation of a photorefractivelike nonlinearity responsible for the formation of giant relief modulations in amorphous semiconductor glasses. The photoinduced softening of the matrix, formation of defects with enhanced polarizability, and their drift under the optical field gradient force is believed to be the origin of the mass transport.
