Optical signal processing techniques employ a wide range of devices and various nonlinearities to achieve multiple network functionalities. The choice of nonlinearity can also impact the relative efficiency, both in terms of energy and material consumption, of the signal processing function being implemented. Techniques for some of the important functionalities, wavelength multicasting, wavelength-division...
We report phase-transparent DQPSK data exchange using parametric depletion in a highly nonlinear fiber. 100-Gbit/s DQPSK data exchange is demonstrated with a power penalty less than 5dB. Pump misalignment tolerance (+/-2ps) and input signal power dynamic range (~20dB) are investigated.
We report the phase-transparent optical data exchange based on non-degenerate FWM in an HNLF via theoretical analysis and experimental verification. 40-Gbit/s NRZ-DPSK data exchange is demonstrated with a power penalty (at 10-9) ~ 4.5 dB.
We report a novel method for all-optical generation of differential Manchester phase-shift keying (DMCPSK) coding. Multicasting generation of 40 Gbit/s DMCPSK coding is experimentally demonstrated using non-degenerate four-wave mixing (ND-FWM) in a highly nonlinear fiber (HNLF).
We report tunable wavelength multicasting of picosecond pulses based on pulsed pumping four-wave mixing (FWM) in a highly nonlinear fiber (HNLF). By employing two or three input continuous-wave (CW) signals, single-to-dual, single-to-four, and single-to-six channel wavelength conversions are observed in the experiment, taking into account the evolution of CW optical waves into optical pulses during...
