“…Moreover, it is shown that the modulation depth indeed increases when using cascaded MRMs, but the insertion loss inevitably increases as well, as discussed in [5]. The capacitance of each MRM is calculated [7] to be 6.2 fF, which gives a power consumption of 45 fJ/bit for the cascaded system [4].…”

“…Aiming at the next generation of optical communication systems, MRMs have been used to demonstrate complex modulation formats, e.g. 80 Gb/s pulse amplitude modulation (PAM-4) [4]. Advanced modulation formats, such as PAM, are advantageous since they provide higher spectral efficiency, i.e.…”

“…Still, it is not possible to fully eliminate the SPM-induced negative-magnitude chirp components, which are directly associated with the SOA pattern effect, but only reduce the variations of their uneven peaks [31]. By calculating the maximum chirp variation, which occurs in the transition between the last '0' in a run of spaces and the '1' that immediately follows, we can extract the chirp parameter at the filters' output similarly to the numerical procedure described in [66]. The value of this parameter is positive and is larger for the ODI than for the MRR.…”

Comparison of Basic Notch Filters for Semiconductor Optical Amplifier Pattern Effect Mitigation

Abstract:We conduct a thorough comparison of two basic notch filters employed to mitigate the pattern effect that manifests when semiconductor optical amplifiers (SOAs) serve linear amplification purposes. The filters are implemented using as the building architecture the optical delay interferometer (ODI) and the microring resonator (MRR). We formulate and follow a rational procedure, which involves identifying and applying the appropriate conditions for the filters' spectral response slope related to the SOA pattern effect suppression mechanism. We thus extract the values of the free spectral range and detuning of each filter, which allow one to equivocally realize the pursued comparison. We define suitable performance metrics and obtain simulation results for each filter. The quantitative comparison reveals that most employed metrics are better with the MRR than with the ODI. Although the difference in performance is small, it is sufficient to justify considering also using the MRR for the intended purpose. Finally, we concisely discuss practical implementation issues of these notch filters and further make a qualitative comparison between them in terms of their inherent advantages and disadvantages. This discussion reveals that each scheme has distinct features that render it appropriate for supporting SOA direct signal amplification applications with a suppressed pattern effect.

“…In terms of the principal requirements for intra-chip interconnects of low power consumption, high bandwidth and small footprint, microring modulators, with dynamic energy consumption in the order of 10 fJ/bit [32], are one of the most promising candidates for optical modulators for intra-chip optical interconnects. The schematic of the demonstration network reported in this paper using two microring modulators, two germanium photodetectors (Ge PDs) and a MDM link is shown in Fig.…”

Abstract-Optical interconnect is a potential solution to attain the large bandwidth on-chip communications needed in high performance computers in a low power and low cost manner. Mode-division multiplexing (MDM) is an emerging technology that scales the capacity of a single wavelength carrier by the number of modes in a multimode waveguide, and is attractive as a cost-effective means for high bandwidth density on-chip communications. Advanced modulation formats with high spectral efficiency in MDM networks can further improve the data rates of the optical link. Here, we demonstrate an intra-chip MDM communications link employing advanced modulation formats with two waveguide modes. We demonstrate a compact single wavelength carrier link that is expected to support 2x100 Gb/s mode multiplexed capacity. The network comprised integrated microring modulators at the transmitter, mode multiplexers, multimode waveguide interconnect, mode demultiplexers and integrated germanium on silicon photodetectors. Each of the mode channels achieves 100 Gb/s line rate with 84 Gb/s net payload data rate at 7% overhead for hard-decision forward error correction (HD-FEC) in the OFDM/16-QAM signal transmission.
