- 論文の詳細を見る
An insertion loss, branching deviation and polarization dependent loss (PDL) as to a 2×N optical splitter using silica-based planar lightwave circuits has been investigated. New key technologies such as (1) a novel wedge type Y-branch, (2) an offset waveguide at the junction between the curved input waveguide and the Y-branch, and (3) low birefringence waveguides due to the appropriate dopant concentration of a cladding, have been devised and incorporated into the splitter. As a result, 2×N optical splitters with low average insertion loss (lt13.2dB), low branching deviation (lt±0.4dB) and low PDL (lt0.2dB) have been successfully developed.
