“…On top of this, Si 3 N 4 waveguides have shown compatibility with efficient thermo-optics tuning and is a CMOS compatible material. While silicon also tick some of the boxes and successful wavelength multicasting has been demonstrated in this platform [22,23], the propagation loss of a typical SOI nanowires is relatively high (2-3 dB/cm) [24] and they suffer from TPA and FCA [4,19]. These losses might be prohibitive for creating an efficient nonlinear IMWP processor.…”

Abstract-Harnessing nonlinear optical effects in a photonic chip scale has been proven useful for a number of key applications in optical communications. Microwave photonics can also benefit from the adoption of such a technology, creating a new concept of nonlinear integrated microwave photonics. Here, we discuss the potential of on-chip nonlinear processing towards the creation of robust and multifunctional microwave photonic (MWP) processors. We also highlight key recent results in the field, including frequency agile MWP filters and ultrawideband signal generators.

“…Furthermore, silicon based wavelength conversion has attracted considerable research interest lately, due to its complementary metal-oxide-semiconductor (CMOS) compatibility, ultra-compactness and potential for integration with electronics [3][4][5][6][7][8][9][10][11][12][13]. One method for silicon based wavelength conversion is using four wave mixing (FWM), which usually requires broadband phase matching [3][4][5][6][7][8][9].…”

Abstract:We build a forward error correction (FEC) module and implement it in an optical signal processing experiment. The experiment consists of two cascaded nonlinear optical signal processes, 160 Gbit/s all optical wavelength conversion based on the cross phase modulation (XPM) in a silicon nanowire and subsequent 160 Gbit/s-to-10 Gbit/s demultiplexing in a highly nonlinear fiber (HNLF). The XPM based all optical wavelength conversion in silicon is achieved by off-center filtering the red shifted sideband on the CW probe. We thoroughly demonstrate and verify that the FEC code operates correctly after the optical signal processing, yielding truly error-free 150 Gbit/s (excl. overhead) optically signal processed data after the two cascaded nonlinear processes.

“…However, sixteen continuous wave (CW) tunable laser sources (TLSs) are needed to act as input signals and phase information is not preserved in the converted signals. Previously, we have demonstrated one-to-six multicasting operation based on dual-pump FWM in a silicon nanowire [11]. The FWM process is normally highly polarization dependent and an efficient FWM process only occurs when the input signal and pump waves are both aligned to either transverse-electric (TE) mode or transverse-magnetic (TM) mode.…”

“…There are six output signals (including the output signal at λ s ), indicated by the arrows in Fig. 2, which satisfy the mentioned phase preserving requirement and thus can be decoded, resulting in the same phase information as the original DPSK data [11]. Therefore, one-to-six multicasting of the DPSK signal is achieved.…”

Abstract:We present polarization insensitive one-to-six WDM multicasting based on nondegenerate four-wave mixing in a silicon nanowire with angled-pump scheme. Bit-error rate measurements are performed and error-free operation is achieved. IntroductionMulticasting is an important feature in a communication network, which can efficiently send a stream of information from a single source to multiple destinations [1], [2]. By using multicasting technology, the amount of network resources can be significantly reduced compared to unicast only networks. Optical layer multicasting could be implemented at a fixed wavelength by power splitting. An alternative is optical wavelength division multiplexing (WDM) multicasting, i.e., multicasting to different wavelengths. One of the most addressed techniques for WDM multicasting is all-optical multi-wavelength conversion (MWC), which replicates signals from one wavelength on multiple wavelengths. WDM multicasting has been demonstrated in different devices including semiconductor optical amplifiers (SOAs) Recently, wavelength conversion in silicon nanowires has attracted considerable research interest due to its compactness, large conversion bandwidth [7] and complementary metal-oxide-semiconductor (CMOS) compatibility. Silicon nanowires have been utilized to demonstrate wavelength conversion at data rates from 10 Gb/s [8] to 640 Gb/s [9], and a sixteen-way multicasting operation of 40 Gb/s non return-to-zero (NRZ) data has also been demonstrated in silicon nanowires [10]. However, sixteen continuous wave (CW) tunable laser sources (TLSs) are needed to act as input signals and phase information is not preserved in the converted signals. Previously, we have demonstrated one-to-six multicasting operation based on dual-pump FWM in a silicon nanowire [11]. The FWM process is normally highly polarization dependent and an efficient FWM process only occurs when the input signal and pump waves are both aligned to either transverse-electric (TE) mode or transverse-magnetic (TM) mode. However, a polarization insensitive operation is desired since the state of polarization (SOP) of the input signal fluctuates with time and distance in a real transmission system.[In this paper, we report polarization-insensitive one-to-six WDM multicasting of 10 Gb/s differential phaseshift-keying (DPSK) data based on dual-pump FWM in a silicon nanowire using an angled-pump scheme [12]. Error-free performance is achieved for all six multicast signals while the polarization of the input data signal is continuously scrambled.
