A first optical manifestation of the Chen-Lee-Liu-type derivative nonlinear Schroedinger equation results in self-steepening of ultrashort pulses and shock formation without simultaneous self-phase modulation. Experiments verify theory. 
Modulational instability characteristics for few cycle pulse propagation in cascaded-quadratic-cubic-quintic nonlinear media
Using phase amplitude ansatz method and standard linear stability analysis, we have investigated modulational instability (MI) for the ultrashort pulse propagation in cascaded quadratic-cubic-quintic
Ultrafast temporal pulse shaping via phase-sensitive three-wave mixing.
TLDR
It is found that the use of phase-sensitive OPA shows a potential for significant compression of approximately 100 fs pulses, steepening of the rise time of ultrashort pulses, and production of pulse doublets and pulse trains.

The second-type derivative nonlinear Schrödinger (DNLSII) equation was introduced as an integrable model in 1979. Very recently, the DNLSII equation has been shown by an experiment to be a model of

Instability of the solitary waves for the generalized derivative nonlinear Schr\"odinger equation in the degenerate case
In this paper, we develop the modulation analysis, the perturbation argument and the Virial identity similar as those in \cite{MartelM:Instab:gKdV} to show the orbital instability of the solitary
Global Well-Posedness on a generalized derivative nonlinear Schr\"odinger equation
We prove global well-posedness for a generalized derivative nonlinear Schr\"odinger equation (gDNLS) by a variational argument. The variational argument is applicable to a cubic derivative nonlinear
