Abstract
A color splitter, a method of manufacturing the same, and an image sensor including the same are disclosed. The color splitter includes: a color separation element that is formed of a sol-gel material having a high refractive index and exhibits a color separation characteristic; and a low-refractive index layer that has a space in which the color separation element is disposed.
Claims20
A color splitter comprising:
- a color separation element that is formed of a sol-gel material having a high refractive index and exhibits a color separation characteristic;
- and
- a low-refractive index layer formed to surround the color separation element.
An image sensor comprising:
- a detection element array comprising a detection elements that have a two-dimensional pixel arrangement and detect incident light;
- and
- a color splitter array comprising a plurality of color splitters which are two-dimensionally arranged and separate incident light according to wavelengths such that light of different wavelengths is incident to different pixels of the detection element array,
- wherein the color splitter array comprises:
- a color separation element that is formed of a sol-gel material having a high refractive index and exhibits a color separation characteristic, the color separation element comprising a plurality of color separation sub-elements that are spaced apart from one another so as to form an array;
- and
- a low-refractive index layer formed to surround the color separation element.
4 more elements
A method of manufacturing a color splitter, the method comprising:
- forming a color separation element by using a sol-gel material having a high refractive index so as to exhibit a color separation characteristic;
- and
- forming a low-refractive index layer formed to surround the color separation element.
