Abstract

Nonlinear fiber Sagnac interferometer switches (NSISs) are of great interest because of their femtosecond response time and low required control power that allows the use of compact laser diodes.^1-3 Wavelength-sensitive couplers in NSISs, however, are traditionally made with bulk-optic² or fiber-optic^1-3 configurations that have disadvantages in terms of limited integration potential, stability, tunability, productivity, and compactness. This paper reports a NSIS with an integrated silica-based planar lightwave circuit⁴ (PLC) that overcomes these problems and demonstrates diode-pumped time- division demultiplexing at 50.4 Gbit/s.
