TL;DR: The results underscore the relatively large optical nonlinearity of BP with unique polarization and thickness dependence, and its potential for polarized optical pulse generation, paving the way to BP based nonlinear and ultrafast photonic applications (e.g., ultrafast all-optical polarization switches/modulators, frequency converters etc.).

TL;DR: In this article, the linear and nonlinear optical properties of black phosphorus thin films are investigated and shown to be controllable by the thickness of the thin film, indicating that the properties can be tuned by the film thickness.

TL;DR: In this article, a liquid phase exfoliation-based approach for the production of few-layer black phosphorus (FL-BP) and subsequent mixing with polycarbonate (PC) for the fabrication of a composite, which significantly reduced BP degradation by PC passivation.

TL;DR: This work reports a wavelength and pulse-duration tunable mode-locked Erbium doped fiber laser with single wall carbon nanotube-based saturable absorber that provides a novel light source for various applications requiring variable wavelength or pulse duration.

TL;DR: In this article, the authors reported the first actively Q-switched laser with a GEOM, which achieved high-repetition-rate, electrically modulated ultrafast pulses with output energies of up to 123 nJ.
