We experimentally demonstrate reconfigurable switching of four 10-Gb/s tributary channels of 40-Gb/s data using a programmable planar lightwave circuit and nonlinear wavelength conversion. Our device ...
We demonstrate parametric conversion with simultaneous 19.5dB amplification, of a mid-IR 2440nm signal to the telecom-band near 1620nm, using silicon nanophotonic wires.Conversion over 820nm is facili...
We measure bit-error rates of polarization-multiplexed Nyquist-WDM QPSK signals,which have rectangular spectral shapes and channel spacing equal to the symbol rate. The spectral efficiency of 4 bit/s/...
We demonstrate multi-impairment monitoring of 640 Gb/s signals enabled by a broadband photonic-chip-based radio-frequency spectrum analyser. We show simultaneous monitoring of group velocity dispersio...
Optical processing in fiber has enabled recent advances such as large, tuneable signal delays, the shifting of signals to mid-IR wavelengths, and the creation of specific quantum states useful in sens...
Simultaneous noise suppression of time-interleaved three-wavelength optical signals using saturation of four-wave mixing in a fiber is reported. Nonlinear phase noise reduction of three-wavelength DPS...
