“…Using this all-fiberized polarization insensitive linear technique, we have successfully demonstrated the application of pulse reshaping for optical regeneration/retiming [2], [3], demultiplexing [4], and optimal pulse compression [5]. In this letter, we demonstrate a simple, cost-effective, alloptical wavelength converter based on self-phase modulation (SPM) and offset filtering which is particularly suited for applications in which the required wavelength shift is modest [6]. We then study and experimentally demonstrate that a saw-toothshaped input signal (asymmetric triangular pulse) is the optimal choice of pulse shape to enhance the efficiency of such a system.…”

Abstract-We experimentally demonstrate the generation of picosecond triangular optical pulses using a superstructured fiber Bragg grating and show experimentally that use of this pulse shape can provide a three-fold improvement in conversion efficiency relative to the use of Gaussian pulses with similar pulsewidths when used in a wavelength conversion scheme based on self-phase modulation and subsequent offset filtering.Index Terms-Fiber Bragg grating, highly nonlinear fiber (HNLF), optical Kerr effect, optical pulse shaping, self-phase modulation (SPM).

“…Instead, OSP appears better suited for much higher data rates where it can allow for large amounts of data to be processed simultaneously in a single device with an associated low switching energy per bit [6]. Examples of this type of OSP are wavelength conversion [7] or regeneration [8]. For such OSP functionalities, the potentially lowest energy per bit could be obtained for the ultra-highspeed serial rates that can be generated by OTDM.…”

Abstract:We demonstrate conversion from 64 × 10 Gbit/s optical timedivision multiplexed (OTDM) data to dense wavelength division multiplexed (DWDM) data with 25 GHz spacing. The conversion is achieved by time-domain optical Fourier transformation (OFT) based on four-wave mixing (FWM) in a 3.6 mm long silicon nanowire. A total of 40 out of 64 tributaries of a 64 × 10 Gbit/s OTDM-DPSK data signal are simultaneously converted with a bit-error rate (BER) performance below the 2 × 10 −3 FEC limit. Using a 50 m long highly nonlinear fiber (HNLF) for higher FWM conversion efficiency, 43 tributaries of a 64 × 10 Gbit/s OTDM-OOK data signal are converted with error-free performance (BER<10 −9 ). ©2011 Optical Society of America

“…The various schemes applicable to return-to-zero (RZ) wavelength conversion so far reported have primarily exploited nonlinear effects in semiconductor optical amplifiers [1] or in fibers. For the latter case, the nonlinear process can be either four wave mixing (FWM) [2], XPM in an interferometric [3] or non interferometric [4] configuration, or self-phase modulation (SPM) if the required wavelength shift from the original signal is modest [5]. Among these possible alternatives, the technique based on XPM-induced sidebands onto a continuous wave (CW) beam (at the desired wavelength), which can then be filtered to provide a wavelength converted representation of the original signal, represents a particularly robust and simple solution.…”

-We experimentally demonstrate the use of sawtooth optical pulses, generated using a superstructured fiber Bragg grating (SSFBG), to achieve high performance and efficient all-optical wavelength conversion in a scheme based on cross-phase modulation (XPM) in a highly nonlinear fiber (HNLF), with subsequent offset filtering. Compared to the use of more conventional waveforms, such as Gaussian pulses, the purpose-shaped saw-tooth pulses allow an improvement in the optical signal to noise ratio (OSNR) of the wavelength converted signal of around 15dB as well as a more than 6dB improvement in receiver sensitivity.
