Optical component

An optical component comprising:

• a first block having a first refractive index and having a first reflective surface;
• a first light absorbing member containing a first metal ion that absorbs light having a first specific wavelength, the first light absorbing member having a second refractive index different from the first refractive index;
• and
• a first buffer layer between and in contact with each of the first light absorbing member and the first block, the first buffer layer having a third refractive index having a value between the first refractive index and the second refractive index,
• wherein
• the first light absorbing member, the first buffer layer, and the first block are arranged in this order in a first direction such that the first block reflects light traveling in the first direction in a second direction different from the first direction on the first reflective surface, or the first block reflects light traveling in a third direction opposite to the second direction in a fourth direction opposite to the first direction on the first reflective surface.
