OPTICAL COMPONENT, OPTICAL CONNECTION COMPONENT WITH GRADIENT INDEX LENS, AND METHOD FOR MANUFACTURING OPTICAL COMPONENT

WIPO Patent Application WO/2020/004354

A1

The purpose of the present invention is to achieve a small and easy-to-assemble arrayed structure for an optical component having an NA conversion function without reducing product yield. An optical component (91) according to the present invention employs a capillary lens array wherein a glass capillary (10) covers the periphery of a plurality of gradient index lenses (20). The refractive index distribution constant (gA) of the plurality of gradient index lenses (20) at one end (PA) of the optical component (91) along the optical axis direction of the gradient index lenses (20) is smaller than the refractive index distribution constant (gB) of the plurality of gradient index lenses (20) at the other end (PB) of the optical component (91) along the optical axis direction of the gradient index lenses (20).
