E. Tangdiongga et al., Interferometric crosstalk reduction by phase scrambling in WDM integrated cross-connects, ELECTR LETT, 36(13), 2000, pp. 1132-1133
Interferometric crosstalk mitigation in a four-channel 2.5Gbit/s InP-based
2 x 2 cross-connect using phase scrambling is reported. Bit error rate perf
ormance is unproved from a large power penalty indicated by a floor at 10(-
8) to a penalty of < 1dB.
