Abstract

We report here in detail the WDM performance of a wide-angle novel X-junction switch (TSXB) that we developed earlier. At a full branching angle of 1.5°, our new design achieves a bandwidth of 145 nm (1470-1615 nm) at 1.5 dB over which the crosstalk is kept below -18.0 dB. Maintaining the same order of bandwidth in normal X-junctions (NXB) requires a branching angle as narrow as 0.2°. A TSXB is thus suitable for WDM systems, yet comes in a size significantly more wide angle (and hence more compact) than an NXB.
