When we think of digital signals, we naturally think of logic highs and lows, signals rooted in the Fourier components of a square wave. Of course, we also know it’s not like that. At gigabit per ...

ISI (inter-symbol interference) closes eye diagrams at high data rates. The skin effect and dispersion—the frequency dependence of the dielectric “constant”—combine to cause the messy low-pass nature ...

Optical Nyquist pulse generation and transmission have emerged as pivotal technologies in the pursuit of maximising data throughput and optimising spectral efficiency in modern fibre‐optic ...
