Abstract: An optical member that includes: a first optical element including a first medium and a first plurality of fillers in the first medium and having a non-spherical shape that changes a traveling direction of light passing through the first medium; and a holding portion configured to hold an optical fiber such that the light emitted from the first optical element enters an end surface of the optical fiber.

Abstract: An optical component including: a first block having a first refractive index and a first reflective surface; a first light absorbing member containing a first metal ion that absorbs light having a first specific wavelength and has a second refractive index different from the first refractive index; a first buffer layer between and in contact with each of the first light absorbing member and the first block, and 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 first block reflects light traveling in the first direction in a second direction different from the first direction on the first reflective surface.

Abstract: An optical coupler that includes: a first optical member including one or more condensing lenses that concentrate light traveling in a positive direction of an X-axis; a fixing unit that fixes one or more optical fibers; and a support member having a first portion extending in the X-axis direction, a second portion extending in the X-axis direction, and a third portion extending in a Y-axis direction orthogonal to the X-axis direction. The third portion, the first optical member, and the fixing unit are arranged at intervals in this order in a positive direction of an X-axis. The third portion, the first optical member, and the fixing unit are positioned between the first portion and the second portion as viewed in the Z-axis direction. The third portion, the first optical member, and the fixing unit are fixed to the first portion and the second portion.
