Photorefractive effect

{
  "id": "MLC-T-CHM-008919",
  "term": "Photorefractive effect",
  "field": "Chemistry",
  "definition": "A phenomenon in which the refractive index of a material changes upon exposure to light, leading to the formation of a temporary phase grating. This change is caused by the spatial redistribution of charge carriers within the material, which then creates an internal electric field. The electro-optic effect then translates this field into a refractive index modulation, with bismuth silicon oxide (BSO) being a common material exhibiting this effect.",
