Ultrafast optics has undergone a revolution in the past two decades, driven by new methods
of pulse generation, amplification, manipulation, and measurement. We review the …

Ultrashort pulse generation hinges on the careful management of dispersion. Traditionally,
this has exclusively involved second-order dispersion, with higher-order dispersion treated …

Nonlinear optical effects are typically weak and enhancement techniques are often required
for practical applications. Here we introduce a method to enhance such effects by …

Temporal optical solitons have been the subject of intense research due to their intriguing
physics and applications in ultrafast optics and supercontinuum generation. Conventional …

Solitons are wave packets that can propagate without changing shape by balancing
nonlinear effects with the effects of dispersion. In photonics, they have underpinned …

Real-time tracking of a waveform frequency content is essential for detection and analysis of
fast rare events in communications, radar, radio astronomy, spectroscopy, sensing etc. This …

Solitons are nonlinear waves present in diverse physical systems including plasmas, water
surfaces and optics. In silicon, the presence of two photon absorption and accompanying …

Temporal solitons are optical pulses that arise from the balance of negative group-velocity
dispersion and self-phase modulation. For decades, only quadratic dispersion was …

Building on the concepts developed for femtosecond metrology, this paper proposes a
unified perspective of different techniques for the temporal characterization of attosecond …

We propose a new method for generating flat self-phase modulation (SPM)-broadened
spectra based on seeding a highly nonlinear fiber (HNLF) with chirp-free parabolic pulses …
