“…We can efficiently combat chromatic-dispersion-induced power fading with SSB. To this end, two signals of a Hilberttransform pair drive the modulators in the I and Q branches [24]. We demonstrate experimentally that our SSB modulation is effective for different fiber lengths.…”

We propose and experimentally demonstrate a polarization-insensitive single sideband modulator based on silicon microring modulators (MRM). The proposed modulator splits and modulates the two orthogonal polarization states of an input laser in a loopback structure, with an on-chip silicon polarization splitter rotator (PSR), overcoming the polarization dependence of the silicon photonic modulator. The IQ configuration of the modulator enables single sideband modulation, thus improving the resistance of the modulated signal to chromatic dispersion and extending the transmission reach. The adoption of an MRM relieves the bandwidth limitation in polarizationdiverse versions of SiP Mach-Zehnder modulators (MZM). Our experiments validate the proposed modulator polarization insensitivity and transmission performance.

“…Their combination with optical orthogonal frequency division multiplexing (OFDM), more specifically its single-sideband variant (SSB-OFDM) that makes use of inexpensive direct detection (DD) receivers, and offers tailored spectral loading, high spectral efficiency and increased reach due to its immunity to fiber dispersion [10][11][12][13][14][15], can substantially improve the aggregate throughput of the system. Sinusoidal modulation [16] as well as single channel data transmission [17] have both been demonstrated using RRM assisted SSB-OFDM modulators in Si photonics (SiP) technology, employing laboratory-grade, narrow linewidth optical sources.…”

We introduce an analytical model describing the statistical and spectral properties of laser phase noise induced intensity noise in ring-resonator-based modulation. The model is validated with single sideband orthogonal frequency division multiplexing (SSB-OFDM) implemented with a silicon photonics resonantly-assisted Mach-Zehnder modulator (RA-MZM). Excellent agreement of experimental data with full link simulations, in which phase noise conversion is treated with the analytical model, confirms its validity. Moreover, we demonstrate 30 Gb/s raw data rate transmission with SSB-OFDM over 20 km of single-mode fiber with a bit error ratio below the 20% forward error correction (FEC) limit for three independently run channels of the RA-MZM, each supplied with off-the-shelf 1 MHz linewidth distributed feedback lasers.
