Description
Technical Field
The invention belongs to the technical field of optical fiber communication, and particularly relates to a high-speed coupling lens.
Background
In optical communication, the near field communication usually uses multimode optical fiber, the light source is a VCSEL light source with 850nm, the VCSEL light source is a vertical cavity surface emitting laser, and therefore the coupling lens usually takes the form of COB or array lens. With the increasing transmission rate, the conventional coupling lens has many problems: the aspheric lenses of the conventional coupling lens are respectively positioned on two sides of the 45-degree inclined plane, so that the concentricity of the high-precision lens is difficult to realize, and higher process requirements are provided for injection molding; for a conventional coupling lens, a relatively deep optical fiber jack or MT (multiple terminal) jack exists on one side close to an optical fiber end face, and an aspheric surface profile on one side of the optical fiber end face has great difficulty in injection molding and measurement; whether the COB lens or the array lens, the intensity of the reflected light is required to be small as the transmission rate is increased. At present, the effective means for solving the LENS surface reflection is film coating. The COB lens and the lens of the array lens, which are close to one side of the optical fiber end, have a certain depth, so that high-quality film coating is difficult to realize. For example, publication No. CN106855658B discloses a light splitting device, in which a first collimating lens and a second collimating lens are respectively located at two sides of a 45-degree refraction portion, and the concentricity of the two lenses is difficult to be accurately ensured during injection molding, and the requirement of the injection molding process is high.

The lens is arranged on one side of the reflecting element 201, the first aspheric surface 101 and the second aspheric surface 102 are all arranged on one side of the reflecting element, the concentricity of the two surfaces can be ensured when the lens is manufactured, in addition, when the two surfaces are detected or coated, the interference of other optical surfaces can not be received, and the coating and the detection are easy to realize.
The reflecting element 201 is provided with a reflecting surface 205 corresponding to the first aspheric surface 101 and the second aspheric surface 102. The beam of the VCSEL light source is focused by the lens and then totally reflected by the reflecting surface 205. The reflecting member 201 is provided with an optical fiber insertion hole 202 for inserting an optical fiber 203 corresponding to the reflecting surface 205. The reflected beam is coupled into an optical fiber 203.
