SECURING AN OPTICAL FIBRE IN A V-GROOVE

摘要

To minimise the risk of adhesive resin (20, 21) securing an optical fibre (11) in a silicon V-groove (13, 14) from filling the space under the fibre, which can lead to delamination effects resulting from thermal expansion mismatch, a controlled amount of the resin is dispensed into each of two reservoirs (31) located on either side of the groove from which the resin flows into the groove along feeder channels (32) linking the reservoirs to the groove.
