Microcombs for Ultradense Optical Communications (SpM1F.1)
Presenter: Bill Corcoran, Monash University

Optical microcombs provide a compact and energy-efficient method to generate ultra-high data rate signals from a single light source. We summarize some recent advances in this field, and some future prospects.

Optical data transmission with high spectral efficiency at 44Terabits/s with a soliton crystal micro-comb (SpM1F.2)
Presenter: David Moss, Swinburne University of Technology

We report data transmission over 75km in the lab and a field trial, at 44.2 Tb/s over standard optical fibre using a single integrated chip source, reaching a spectral efficiency of 10.4 bits/s/Hz.

Digital Signal Processing for Subcarrier-Multiplexing Systems (SpM1F.3)
Presenter: Fernando Guiomar, Instituto De Telecomunicacoes

We review the benefits and key aspects in the design of DSP algorithms for subcarrier-multiplexing systems, such as advanced signal modulation, adaptive equalization and polarization demultiplexing, carrier-phase estimation, and nonlinear mitigation.

Low Bandwidth Detection of High Data Rate Nyquist Signals (SpM1F.4)
Presenter: Janosch Meier, TU Braunschweig, IHF

We propose a new signal demultiplexing technique for rectangular, high-bandwidth Nyquist data, that neither for the sampling, nor the electrical signal processing needs any high-bandwidth devices. The method is suited for integration on any platform.

Extending the reach of O-band transmission using Bismuth-doped fibre amplifiers (SpM1F.5)
Presenter: Periklis Petropoulos, University of Southampton

We review recent demonstrations of amplified data transmission in the 1300-nm region. The extension of the reach in high-speed systems necessitates the consideration of modulation techniques that mitigate the onset of chromatic dispersion.
