Quasi-Real-Time Optical Sampling Scheme for High-Speed Signal Acquisition and Processing
- 2013

In: IEEE Photonics Technology Letters. - 1041-1135 .- 1941-0174. ; 25:5, s. 504-507
-
Journal article (peer-reviewed)abstract
- We present a quasi-real-time coherent sampling approach that combines the high-bandwidth and high-fidelity signal acquisition of equivalent-time optical sampling with real-time digital signal processing and equalization algorithms. The quasi-real-time concept enables feasibility studies of optical communication at symbol rates beyond the bandwidth of conventional digitizer approaches. Here we demonstrate the technique using a 107-GBd polarization-division-multiplexed quadrature phase shift keyed signal.

Lossless and muxless frequency comb modulation
- 2020

In: Optics InfoBase Conference Papers. - 2162-2701. ; Part F191-SPPCom 2020
-
Conference paper (peer-reviewed)abstract
- We review optical modulation using temporal reshaping based on segments with interleaved phase modulation and dispersion. The proposed technique is compared to traditional IQmodulators with focus on generating frequency comb-based superchannels.

Conference paper (peer-reviewed)abstract
- Lossless modulation based on unitary spectro-temporal transformations allows modulation of independent waveforms onto lines from a frequency comb without any DeMUX/MUX. We discuss this alternative modulation technique and its application in optical communication and frequency comb generation.

Optical frequency comb modulator for multichannel systems
- 2019
-
In: IET Conference Publications. ; 2019:CP765
-
Conference paper (peer-reviewed)abstract
- We demonstrate a full-field modulator for encoding independent waveforms onto wavelength separated inputs without demultiplexing. The modulator uses phase-only modulation and dispersive filtering for temporal reshaping and has no theoretical losses. Simultaneous modulation of three wavelengths with independent random 1% roll-off data patterns is experimentally verified.
