Plastic optical fibre with two cores |
abstract |
The present invention provides a plastic opticalnfiber comprising a cladding, a first core disposedninside the cladding, and a second core disposed insidenthe first core; wherein a ratio X of a diameter (D2) ofnthe second core to a diameter (D1) of the first coren( =D2/D1 ) and a ratio Y of a difference (n 1 - n 0 ) betweenna refractive index (n 1 ) of the first core and anrefractive index (n 0 ) of the cladding to a differencen(n 2 - n 0 ) between a refractive index of the second coren(n 2 ) and the refractive index (n 0 ) of the cladding ( =(n 1 n- n 0 )/(n 2 - n 0 ) ) satisfy the following relationalnexpressions: 0.3 ≤ X ≤ 0.95, 0.4 ≤ Y ≤ 0.95,n1 ≤ X + Y ≤ 1.9. |
