Paper Abstract

We report in-house development of a real time monitoring system with programmable fabrication parameters for fabricating fused-fiber coupler based branching components. A number of branching components of varied specifications and with fibers of different make have been fabricated; these exhibited low excess loss and other features akin to commercially available couplers. Fabricated WDM couplers for operation at 1310/1550 nm exhibited high degree of isolation, large isolation bandwidth and reasonably low excess loss. Characteristics of the fabricated couplers have been investigated for optimizing design and fabrication parameters with regard to channel isolation and excess loss in the device. An equivalent planar waveguide (EPG) model has also been used to model these couplers and to correlate with the experimental findings.
