The impact of noise in the pump profile of distributed Raman amplifier (DRA) for extended bandwidth transmissions is investigated. Specifically, a continuous pump generated by a shaped amplified spontaneous emission signal is employed to fit the DRA gain profile to a predefined target. The analysis is performed by comparing the power profiles obtained by the artificial neural networks (ANN) and by conventional numerical models for the Raman amplification process, resulting in errors below 0.5 dB.

The Kerr- related nonlinear signal distortion for unrepeatered optical links is evaluated for a 100-Gb/s single-channel scenario supported by first-order distributed Raman amplification. The results, comparing systems performance in terms of bit error rate for several optical fibers with dissimilar characteristics, indicate the importance to balance nonlinear and noise degradation to fully optimize the reach and capacity of this kind of system.

The use of plastic optical fibers has become widespread due to their mechanical advantages and low cost, despite presenting considerable dispersion. This paper models an OFDM transmission link using the signal power, the bias current and the fiber length over an Extreme Gradient Boost regressor by fitting the multicarrier signal-to-noise ratio. The results show an improvement in the coefficient of determination, and in the error metrics, when compared to traditional modeling.

We report on curvature sensing measurements using a hybrid Kagomé-tubular hollow-core photonic crystal fiber. The sensing principle is based on bending-mediated resonant couplings between core and airy cladding modes achieved at specific curvature radii and wavelengths. We consider that our investigation identifies a promising use of hollow-core fibers in sensing, thus broadening the application framework of this family of fibers.

We investigated an inkjet-printed polymer optical resonator as an environmental sensor. The fabrication method combines additive manufacturing and microfabrication techniques to obtain a suspended SU-8 microdroplet on a silicon pillar. Sensitivity for temperature (−41.4 pm/°C) and humidity sensitivity (0.22 pm/ppm) are measured.

In this work we study a microchip laser designed to function as an oscillator in a Master-Oscillator Power-Amplifier (MOPA) system targeted for laser tattoo removal. Different configurations of the Nd: YAG resonator were used by changing the output coupler mirror reflectivities and the initial transmission of the Q-switch. The quasi-CW resonator provided 55.4 W of output with 51.31% and 78.2% optical and slope efficiencies, respectively. For Q-switched operation, the best configuration resulted in a peak output power of 3.6 MW with 588 ps pulse width.

Nitrogen-doped carbon nanodots synthesized from L-arginine and ethylenediamine (NCNDs) were combined to PMMA for obtaining fluorescent nanocomposites. Since this photoluminescence could increase the efficiency of solar energy concentrators and generators, photovoltaic cells were coated with such materials. Even using a setup with low contact of the optical polymer film on silicon surface, a promising 11.3% increase of cell efficiency was observed, showing the feasibility and potential for application of these environmentally friendly materials.

Cavity modes have fundamental importance in nanophotonics as in the two-dimensional (2D) crystals' optical response supporting subwavelength polaritons. Typically, high momenta polaritons in 2D crystals create cavity modes dependent on boundary conditions dictated by the material geometrical forms, substrate electrical permittivity and the optical probes used to interrogate the phenomenon. Here, we use a synchrotron infrared nanospectroscopy to probe polaritonic cavities in hexagonal boron nitride 2D crystals lying on metallic and dielectric substrates. From theoretical approach in quantitative agreement with experimental real-space imaging of polariton waves, we derive the dispersion relation and the reflection/transition coefficients governing the polaritonic cavities.
