    • Provided are an optical coupler and an active optical module including the same. The optical coupler includes at least one first optical fiber, a second optical fiber, and a hollow optical block. The at least one first optical fiber transfers pump light. The second optical fiber includes a cladding with a facet enlarged from a first outer diameter to a second outer diameter, and passes the pump light which is transferred through the first optical fiber. The hollow optical block includes a through hole, an incident surface, and a coupling surface. The through hole passes the cladding with the first outer diameter. The incident surface is connected to the first optical fiber at a side end of the through hole. The coupling surface is joined to the facet of the second optical fiber at the other side end of the through hole facing the incident surface.
    • 提供一种光耦合器和包括该光耦合器的有源光学模块。 光耦合器包括至少一个第一光纤,第二光纤和中空光学块。 所述至少一个第一光纤传送泵浦光。 第二光纤包括具有从第一外径扩大到第二外径的小面的包层,并使通过第一光纤传送的泵浦光通过。 中空光学块包括通孔,入射表面和联接表面。 通孔通过具有第一外径的包层。 入射面在通孔的侧端连接到第一光纤。 耦合面在面向入射面的通孔的另一侧端部与第二光纤的面连接。
