Black phosphorus: a two-dimension saturable absorption material for mid-infrared Q-switched and mode-locked fiber lasers
TL;DR: The simple and effective liquid phase exfoliation (LPE) method was used to fabricate black phosphorus as the saturable absorber (SA) into two specifically designed rare earth ions doped fluoride fiber lasers at mid-infrared wavebands.
Journal ArticleDOI
Electro-absorption optical modulator using dual-graphene-on-graphene configuration
TL;DR: By optimizing the position of each graphene-on-graphene (GOG) layer in theWaveguide, a strong interaction between graphene layers and light is obtained, which leads to a significant change of the effective mode index (EMI) in the waveguide.
Journal ArticleDOI
Tunable and switchable dual-wavelength mode-locked Tm 3+ -doped fiber laser based on a fiber taper
TL;DR: A self-starting dual-wavelength mode-locked fiber laser at a 2 μm spectral region is demonstrated by using a fiber taper in a Tm3+-doped ring fiber cavity by inserting a 10.0 m dispersion compensation fiber into the fiber cavity.
Journal ArticleDOI
High-Speed Optical Phase Modulator Based on Graphene-Silicon Waveguide
TL;DR: In this paper, a high-speed optical phase modulator based on graphene-silicon waveguide (GSW) is presented, where two graphene flakes, sandwiched by insulating dielectric spacers, are embedded in a silicon waveguide to enhance the interaction between the graphene and light.
Journal ArticleDOI
Waveguide Engineering of Graphene Optoelectronics—Modulators and Polarizers
TL;DR: In this article, the authors theoretically demonstrate that by altering the dimension design of graphene-laminated silicon waveguides, the phase, amplitude, and polarization of the fundamental propagating modes can all be effectively tailored under different bias voltages.
