摘要
An optical coupler (100) includes a first optical port (110) , a second optical port (120) , a third optical port (130) , and a fourth optical port (140) . The optical coupler further includes a photonic-bandgap fiber (150) having a cladding (160) , a first core (170) , and a second core (180) . The cladding includes a material with a first refractive index and regions within the cladding. The regions have a second refractive index lower than the first refractive index. The first core is substantially surrounded by the cladding. The first core is optically coupled to the first optical port and to the second optical port. The second core is substantially surrounded by the cladding. The second core is optically coupled to the third optical port and to the fourth optical port. At least a portion of the first core is generally parallel to and spaced from at least a portion of the second core such that the first core is optically coupled to the second core. The first core, the second core, or both the first core and the second core is hollow.
