TLDR
In this paper, the optical trench structure is made of low dielectric constant material with an index of refraction that is less than the index of the material of surrounding layers (e.g., the substrate).Abstract:
A device and method for providing an optical trench structure for a pixel which guides incoming light onto the photosensor of the pixel. The optical trench structure has an optically reflecting barrier that substantially mitigates optical crosstalk. The optical trench structure is made of low dielectric constant material with an index of refraction that is less than the index of refraction of the material of surrounding layers (e.g., the substrate). This difference in refractive index causes an internal reflection into an optical path existing between a lens and pixel.read more
