Two substrates, sand and vermiculite, were tested in rearing laboratory experiments with Reticulitermes grassei at different culture periods (2, 4 and 6 weeks). Although information is available regarding procedures to keep species of Reticulitermes

We present a wavelength division multiplexing-passive optical network (WDM-PON) that uses a graphene-based ultrashort pulsed fiber laser (USPL) as multi-wavelength source. The performance of this WDM-PON system is analyzed in two stages: at first, th

We propose and numerically analyze a colorless transmitter based on a Fabry-Perot Laser Diode in a WDM-PON. We study the power requirements for achieving a SMSR around 30 dB for different injected carrier linewidths.

We propose a graphene-based multi-wavelength source for WDM-PON applications. The transmission performance is evaluated in comparison with a Flat Combs Generator based on a Mach-Zehnder-Modulator obtaining distance penalties less than 5 km at BER 10�

Graphene and 2D materials are being used in the design of light sources due to their wide absorption spectrum, ultrafast recovery time and high modulation depth. In this work, we present a experimental design of an modelocking Erbium-Doped-Fiber-Lase

We report on measurements of high-order dispersion maps of an optical fiber, showing how the ratio between the third and fourth-order dispersion (β3/β4) and the zero-dispersion wavelength (λ0) vary along the length of the fiber. Our method is base

We analyze spiral nano-waveguides providing parametric gain in meter long lengths with millimetric footprint, considering robustness against fluctuations of core dimensions and curvature dependence of the dispersion parameters. We discuss an example

We present a study on the characterization and quality evaluation of all-fiber chemical vapor deposition (CVD) graphene saturable absorber samples for Erbium-doped fiber laser (EDFL) mode locking. Optical fiber end faces covered by CVD graphene were

Optical Frequency Comb Generation (OFCG) technique using a Mach Zehnder modulator (MZM) allows to diminish cost of an optical access network based on Wavelength Division Multiplexing (WDM), because it just needs a single source for generating several
