Abstract

We present ultrahigh-speed and full C-band tunable wavelength conversions using cross-gain modulation in a quantum-dot semiconductor optical amplifier (QD-SOA). In this study, we successfully demonstrated error-free 320-Gbit/s operation of an all-optical wavelength converter (AOWC) using the QD-SOA for the first time. We also demonstrated full C-band tunable operation of the AOWC in the wavelength range between 1535 nm and 1565 nm at a bit rate of 160-Gbit/s.

1. Introduction

Quantum-dot semiconductor optical amplifiers (QD-SOAs) have attracted much attention, as they have been shown to be superior to common SOAs in terms of the key attributes needed for an AOWC, such as improved gain, faster recovery time, and broader gain bandwidth [15

]. Recently, a number of high-speed demonstrations highlighting the potential advantages of using QD-SOAs for AOWCs were reported. Four-wave mixing (FWM) can offer higher conversion efficiency over a wider bandwidth, which is needed for AOWCs, in comparison with a common bulk/QW-SOA [16

]. Indeed, we have successfully demonstrated error-free operation of an AOWC at a bit rate of 320-Gbit/s [19

]. However, it was difficult to achieve widely tunable operation. In the AOWC, the available wavelength range was severely limited because the signal spectra of the 320-Gbit/s input and converted signals with the large wavelength spacing required for the FWM process had to be within the available wavelength range. Another promising approach is to use cross-gain modulation (XGM) in a QD-SOA [20

]. An AOWC using XGM has also been demonstrated up to broadband operation covering the S/C/L-bands [20

]. However, no experimental demonstration of the XGM-based AOWC beyond 160-Gbit/s operation has been reported so far, and the performance reported at 160-Gbit/s was not quantified in terms of the bit-error-rate (BER) and tunability.

In this work, we present ultrahigh-speed and widely tunable wavelength conversion by means of XGM using a QD-SOA [24

]. First, we demonstrate low power penalty full C-band wavelength-tunable operation of return-to-zero on-off keying (RZ-OOK) signal at a bit rate of 160-Gbit/s. Next, we demonstrate error-free 320-Gbit/s wavelength conversion by means of XGM in a QD-SOA. Here, we show that QD-SOAs show superior performance in comparison to common SOAs, due to different gain and index dynamics, in particular, a stronger blue chirp. The device we used had a gain recovery of 85% within 10 ps, while the remaining 15% was completely recovered within approximately 100 ps. Consequently, the device introduces strong blue-chirp, which, when properly exploited, leads to ultrahigh-speed operation and low receiver power penalties. We believe that these are only possible because of the much broader gain bandwidth that QD-SOAs have compared to common SOAs.

This paper is organized as follows. Section 2 describes the gain characteristics of the QD-SOA we used. The experimental setup is explained in Section 3. In Section 4, an experimental demonstration of widely tunable operation of the AOWC is presented for 160-Gbit/s followed by a demonstration of ultrahigh-speed operation of the AOWC at 320-Gbit/s. Finally, Section 5 concludes this work.

4.2. Wavelength tunable operation in full C-band at 160-Gbit/s

To investigate the wavelength tunability of the AOWC, we demonstrated the full C-band operation using 160-Gbit/s signals. Figure 4(a)

shows the BER characteristics of the 40-Gbit/s back-to-back (BtoB), 160-Gbit/s input data (original), and converted signals. The wavelength of the input data and CW probe (converted) signals was 1545 nm and 1560 nm, respectively. The center wavelength of the BPF at the output of the QD-SOA was blue-shifted by 5.0 nm to speed up the gain recovery time. The injected power into the QD-SOA of the pump and probe signals was 3.7 dBm and 6.9 dBm, respectively. In all the 40-Gbit/s tributaries, the power penalties at the error-free (BER = 10−9) between the original and converted signals were less than 1.6 dB. Figure 4(b) shows the error-free received powers of the original and converted signals over the entire C-band. In this work, to avoid the large signal spectral overlapping between the input and converted signals, the input wavelength was set to 1545 nm or 1565 nm, according to the converted wavelength. In Fig. 4(b), the average power penalties of less than 2.0 dB could be obtained in the wavelength range between 1540 nm and 1565 nm. On the other hand, the power penalty at the wavelength of 1535 nm was more than 4.0 dB. We believe that this larger penalty was not only due to the QD-SOA performance at shorter wavelengths but also due to the demultiplexing performance of the employed EAM-based DEMUX at 1535 nm.

4.3. Ultrahigh-speed operation at 320-Gbit/s

To evaluate the conversion performance, we measured the BER characteristics of the demultiplexed 40-Gbit/s input data (original) and converted signals, as shown in Fig. 7 (a)
Fig. 7 (a) BER characteristics of original and converted signals in the cases of best (circle) and worst (square). (b) 320-Gbit/s eye-patterns of the original and converted signals. (c) 40-Gbit/s demultiplexed eye-patterns of the original and converted signals.
. For all the eight 40-Gbit/s tributaries, no error floors were observed. The average power penalty for BER = 10−9 between the original and converted signals was approximately 4.2 dB, which were much smaller than that of the 320-Gbit/s AOWC using the common SOA [13

]. Figures 7(b) and 7(c) show the 320-Gbit/s pulse train and demultiplexed 40-Gbit/s eye-patterns of the original and converted signals, respectively. It should be noted that the pulse widths of the demultiplexed original and converted signals were broadened and appeared to the same, compared to the original and converted trains before demultiplexing in Fig. 7(b). This was because of pulse broadening, not by the dispersion of the HNLF in the NOLM, but by the spectral slicing of the BPF located at the tail of the NOLM. Therefore, no performance degradation was observed due to the intersymbol interference of the neighboring channels. The obtained eye-patterns of the converted signals showed clear eye openings, which was consistent with the BER results.

5. Summary

We successfully demonstrated error-free 320-Gbit/s all-optical wavelength conversion using a QD-SOA. To the best of our knowledge, this is the highest bit-rate operation of AOWC using a QD-SOA. We also demonstrated full (1535−1565 nm) C-band tunable operation at 160-Gbit/s. The obtained results indicated that QD-SOAs have higher potential to dramatically improve the conversion performances of AOWCs than common SOAs.
