OPTICAL MEMBER, SOLID-STATE IMAGING DEVICE, AND MANUFACTURING METHOD

摘要

An optical member includes high refractive index layers having a great refractive index and low refractive index layers having a small refractive index, which are each relatively thin as compared with an optical length, disposed alternately in the lateral direction as to an optical axis. Each width of the high refractive index layers and the low refractive index layers is equal to or smaller than the wavelength order of incident light.
