Abstract:
1. An optical connector comprising: a first optical fiber having a core and a clad, a first fixing member having a through-hole for fixing said first optical fiber; a second optical fiber having a core and a clad, and a second fixing member having a through-hole for fixing said second optical fiber; wherein the through-hole of the first fixing member is formed so that a diameter of the through-hole on the side of an end of said first optical fiber is larger than a diameter of the through-hole on a rear side, wherein an end portion of the first optical fiber is bended in the large diameter portion, wherein said end of said first optical fiber and an end of said second optical fiber are connected by connecting the first fixing member and the second fixing member, wherein said first optical fiber is a single mode optical fiber and said second optical fiber is a multimode optical fiber, and said first fixing member and said second fixing member are connected so that the distance between the core center of said first optical fiber and the core center of said second optical fiber is 10 to 25 μm, wherein said optical axis of said first optical fiber is inclined to the optical axis of the second optical fiber, and wherein the light beam entering said second optical fiber from said first optical fiber is inclined by 3 to 25 degrees to the central axis of said second optical fiber.
