“…Therefore, PCFs are very suitable for all-optical time demultiplexing [22][23][24], wavelength conversion [7,18], pulse reshaping and other signal processing functions [18,25]. Recently, Zsigri et al successfully demonstrated the functionalities of broadcasting, transmission and wavelength conversion entirely based on PCFs at a bit rate of 10 Gbit s −1 [26], which will be useful for future all-optical networks. Since the reported broadcasting function was implemented by exploiting cross-phase modulation (XPM) in a nonlinear optical loop mirror (NOLM), the resulting configuration can be complex for practical applications.…”

“…Since the reported broadcasting function was implemented by exploiting cross-phase modulation (XPM) in a nonlinear optical loop mirror (NOLM), the resulting configuration can be complex for practical applications. Moreover, the OTDM scheme has not yet been considered in the work on using PCFs for wavelength conversion and multicasting as reported in [7,18,19,25,26]. However, future all-optical networks will employ OTDM to efficiently increase the data bit rate per wavelength channel in order to reduce the complexity and power consumption of the network.…”

We propose the use of cross-phase modulation (XPM) and four-wave mixing (FWM) in dispersion-flattened highly nonlinear photonic crystal fibers (HNL-PCFs) to implement the functionalities of wavelength conversion, simultaneous time demultiplexing and wavelength multicasting in optical time-division multiplexing (OTDM) systems. The experiments on wavelength conversion at 80 Gbit s−1and OTDM demultiplexing from 80 to 10 Gbit s−1 with wavelength multicasting of two channels are successfully demonstrated to validate the proposed scheme, which are carried out by using two segments of dispersion-flattened HNL-PCFs with lengths of 100 and 50 m, respectively. Moreover, the bit error rate (BER) performance is also measured. The results show that our designed system can achieve a power penalty of less than 4.6 dB for two multicasting channels with a 24 nm wavelength span at the BER of 10−9 when compared with the 10 Gbit/s back-to-back measurement. The proposed system is transparent to bit rate since only an ultrafast third-order nonlinear effect is used. The resulting configuration is compact, robust and reliable, benefiting from the use of dispersion-flattened HNL-PCFs with short lengths. This also makes the proposed system more flexible in the operational wavelengths than those based on dispersion-shifted fibers and traditional highly nonlinear fibers.

“…Highly nonlinear photonic crystal fibers (PCFs) have been recently employed for optical time demultiplexing up to 160 Gbit s −1 [20][21][22], 40 GS s −1 wavelength-division sampling [23], all-optical modulation-format conversion [24], optical signal regeneration [25], wavelength conversion and multicasting [26][27][28][29][30][31][32]. This is because PCFs possess unique properties which are not provided by conventional optical fibers.…”

A novel scheme is proposed for ultrafast optical waveform samplers capable of operating over a wide wavelength range, which uses the four-wave mixing in a highly nonlinear photonic crystal fiber (HNL-PCF) with low and very flat dispersion in the S, C and L bands. We report the first demonstration of the designed optical sampler by employing a 20 m dispersion-flattened HNL-PCF for observing the 160 Gbit s−1 optical data signal to achieve a temporal resolution of less than 0.8 ps for a wavelength separation up to 11 nm between data signal and sampling lights. This preliminary result is mainly restricted by the tunable optical bandpass filter used in our present experiment. The proposed scheme shows a potential for realizing wideband, high-resolution optical waveform sampling systems in a simple configuration and a cost-effective manner by using commercially available optical fibers of short length.

“…This is attractive for all-optical signal processing in future transparent photonic networks. Until now, alloptical wavelength conversion based on FWM in a PCF has been demonstrated at different bit rates [17][18][19][20][21][22]. However, it is noticed that most of the reported works mainly focus on single-to-single channel wavelength conversion, while single-to-multiple wavelength conversion with a multicasting function is highly desirable in practical optical label swapping packet-switched networks.…”

Optical networking applications require the use of all-optical wavelength converters with input and output wavelength tenability as well as large numbers of multicasting channels. This article demonstrates the single-to-multiple wavelength conversion via multiple four-wave mixings between a 10-Gbit/s return-to-zero signal and several continuous waves co-propagating in a dispersion-flattened highly nonlinear photonic crystal fiber. For single-to-single channel wavelength conversion, a wide conversion range of 31 nm is achieved with the optimal conversion efficiency of 21.4 dB. By employing several continuous-wave probe lights, tunable single-todual and single-to-triple channel wavelength conversions are experimentally demonstrated, respectively. Moreover, the dynamic characteristics of the designed wavelength converter are studied under the conditions of variable input powers, polarization mismatch, and different lengths of the highly non-linear-photonic crystal fiber. The system is transparent to both bit rate and modulation format. This is very useful for engineering design and applications of optical-fiber-based wavelength converters in future ultra-high-speed photonic networks.
