Solitons are wave packets that can propagate without changing shape by balancing nonlinear effects with the effects of dispersion. In photonics, they have underpinned numerous applications, ranging from telecommunications and spectroscopy to ultrasho

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 considered with higher order dispersion often thought of as a nuisance. Follo

We demonstrate a $\hbox{Ho}^{3+}$, $\hbox{Pr}^{3+} $ co-doped fluoride fiber laser that produces an output power of 7.2 W, a 150-nm tuning range, and a narrow linewidth of $ nm using a power-scalable $\hbox{Yb}^{3+} $ fiber-laser-pumped 1150-nm Raman

A waveguide array fiber laser is demonstrated. An AlGaAs waveguide array is used as a saturable absorber to achieve passive mode-locking in an erbium-doped fiber laser. The output consists of a very regular train of pulses. Autocorrelations show that

We review our recent work on the generation of novel optical solitons arising from different, high orders of dispersion and combinations thereof. By incorporating a spectral pulse-shaper in a mode-locked laser cavity, we can tailor the net-cavity dis

The authors demonstrate the existence of optical solitons arising from the balance between self-phase modulation and negative, pure, even high-order dispersion using a fiber laser incorporating a spectral pulse shaper.

We investigate theoretically and numerically the self-similar propagation of optical pulses in the presence of gain, positive Kerr nonlinearity, and positive (i.e., normal) dispersion of even order $m$. Starting from a modified nonlinear Schr\"odinge

Cascaded stimulated Brillouin scattering is a complex nonlinear optical process that results in the generation of several optical waves that are frequency shifted by an acoustic resonance frequency. Four-wave mixing (FWM) between these Brillouin shif

We report the generation and characterization of soliton-molecules in dispersion-managed fiber lasers. Solitons at two different frequencies, with common (negative) dispersion, have identical group velocities; these solitons form a bound state with t
