“…In recent years research has focused on engineering devices, which, apart from exhibiting strong nonlinear characteristics, they also possess tightly controlled chromatic dispersion profiles, so that high conversion efficiencies, high signal gains and broad operation bandwidths can be achieved. At the same time, the attraction of realizing ultra-fast low power highly nonlinear integrated devices has recently made silicon photonics a hot research topic [2][3][4][5]. Several demonstrations of nonlinear effects, such as FWM [9,10], third-harmonic generation [11], self-phase modulation [12] and Raman amplification [6][7][8] have already been reported in silicon-on-insulator (SOI) waveguides and nanowires.…”

Abstract:We demonstrate four wave mixing (FWM) based wavelength conversion of 40 Gbaud differential phase shift keyed (DPSK) and quadrature phase shift keyed (QPSK) signals in a 2.5 cm long silicon germanium waveguide. For a 290 mW pump power, bit error ratio (BER) measurements show approximately a 2-dB power penalty in both cases of DPSK (measured at a BER of 10 −9 ) and QPSK (at a BER of 10 −3 ) signals that we examined.

“…Although the operation stability of the resulting demultiplexer is improved, a walk-off between optical pulses or a phase mismatch due to dispersion in traditional HNLFs can still restrict the operational wavelength range of HNLF-based demultiplexers. By utilizing FWM in silicon nanowire [18] and chalcogenide glass waveguide [19], two novel OTDM demultiplexers have been demonstrated recently, which are capable of ultrahigh-speed operation and are very promising for use in the future OTDM systems. These advanced photonic devices, however, require a sophisticated fabrication process which can prevent them from practical applications nowadays.…”

This paper reports a new design of optical time-division multiplexed (OTDM) systems that possess a functionality of simultaneous time demultiplexing and wavelength multicasting based on the cascaded four-wave mixing in a dispersion-flattened highly nonlinear photonic crystal fiber (DF-HNL-PCF). A module of OTDM demultiplexing and wavelength multicasting can be feasibly implemented by using a 3 dB optical coupler, a high-power erbium-doped fiber amplifier, a short-length DF-HNL-PCF, and a wavelength demultiplexer in the simple configuration. We also carry out an experiment on the proposed system to demonstrate the 100–10 Gbit s−1 OTDM demultiplexing with wavelength conversion simultaneously at 4 multicast wavelengths. It is shown that error-free wavelength multicasting is achieved on two wavelength channels with the minimum power penalty of 3.2 dB relative to the 10 Gbit s−1 back-to-back measurement, whereas the bit error rates of other two multicasting channels are measured to be about 10−6–10−5. Moreover, we propose the use of a proper error-correcting code to improve the multicasting performance of such an OTDM system, and our work reveals that the resulting system can theoretically support error-free multicasting of the OTDM-demultiplexed signal on four wavelength channels.
