PHOTOELECTRIC CONVERTER, IMAGING SYSTEM Russian patent published in 2011 - IPC H01L27/14 H01L31/232 

FIELD: physics.

SUBSTANCE: proposed converter comprises multiple photo electric converters with light-sensitive surface, isolating films, multiple light guide sections arranged atop isolating films. Note here that each light guide section directs light onto light-sensitive surface and boundary sections. Note also that each boundary section forms boundary between adjacent light guide sections and is made from material with lower refractivity compared with that of light guide section material. Note also that width of each boundary section does not exceed half the minimum wavelength of visible light, and height from bottom to top surfaces of every light guide section makes at least double maximum wavelength of visible light.

EFFECT: efficient light collection.
