12 January 1998Silica-on-silicon very broadband 8-channel splitter
Power splitters with high performances in a very broad region of wavelengths are key components in Passive Optical Networks. To this end, we designed an 8 channel power divider that works in the range 1260 nm-1650 nm by cascading Y-junctions optimized for low loss operation. Several devices have been fabricated using the silicon technology and then fully characterized on a semi-automatic bench developed on purpose to evaluate the spectral response and polarization dependent losses. Preliminary measurements show that the devices are within ETSI and Bellcore specifications.
