Linear multimode optical systems have enabled clean experimental observations and the
applications of numerous phenomena that continually extend the boundaries of wave …

Softphotonics has emerged as a new discipline that utilizes soft matter (ie, liquids, gels, bio‐
materials) as waveguide materials with versatile functionalities. The flexible properties of soft …

The pulse duration at the output of femtosecond lasers is usually close to the Fourier limit,
and can be shortened by increasing the spectral width. To this end, use is made of self …

The overall goal of photonics research is to understand and control light in new and richer
ways to facilitate new and richer applications. Many major developments to this end have …

The fundamental principles and experimental implementations of multipass cells used as a
platform for nonlinear optics are reviewed. Embedding a nonlinear medium in a multipass …

In this Letter, we investigate the energy-scaling rules of hollow-core fiber (HCF)-based
nonlinear pulse propagation and compression merged with high-energy Yb-laser …

Recent developments in ultrafast laser technology have resulted in novel few-cycle sources
in the mid-infrared. Accurately characterizing the time-dependent intensities and electric …

We demonstrate ultrashort pulse compression from 300 fs down to 17 fs at a repetition rate
of 20 kHz and 160-µJ output pulse energy (3.2 W of average power) using multidimensional …

We investigate soliton self-compression and ultraviolet resonant dispersive wave emission
in the higher-order modes of a gas-filled hollow capillary fibre (HCF). Our simple analytical …

Optical frequency combs are typically generated in the near-infrared wavelength range,
where many mode-locked lasers operate. Nonlinear frequency conversion can then be used …
