Optical waveguide and an image sensor using the same

摘要

An optical waveguide and an image sensor using the same, the optical waveguide comprising a plurality of bar-shaped cores that are aligned in a proper manner, the cores being made of transparent materials with a large refractive index, and a cladding that is disposed around the cores, the cladding being made of materials with a small refractive index that are capable of absorbing or scattering light, wherein part of each of said cores on which irradiated light is incident is uncovered, or part of said cladding on which irradiated light is incident is transparent.
