This paper demonstrates a simple piano-inspired interface to play a full C major scale based on a optical fiber specklegram quasi-distributed sensor. The user inputs musical notes via foam pads over one multimode optical fiber connected to a laser source and a webcam. Correlating the reference and immediate specklegrams retrieves the note input, subsequently played via audio output connected to the webcam. The interface is demonstrated with a precision of ~0.94 % for eight musical notes plus a neutral state and does not depend on the input order.

To verify and validate the use of machine learning techniques for chromatic dispersion compensation, we developed an end-to-end recurrent neural network (RNN) to replace the digital signal processing (DSP) blocks used in optical transmission and reception. We also evaluated the sensitivity of the developed networks to certain hyperparameters. Our analysis indicated that the number of neurons and the number of epochs were the most impactful parameters, and we also observed that using lower values for these parameters resulted in performance that was closer to that of a conventional DSP implementation.

We investigate the potential of IT’-MoTe2 as a saturable absorber for silicon photonics devices. By optimizing the coupling coefficient between the 2D material and the wave-guide, we achieve a maximum coupling of 18%. Utilizing carrier statistics calculations, we estimate the saturation intensity per effective interaction length as 7.5MW/cm2·nm at 1560nm. Our simulation suggests that the saturation intensity in an optimized waveguide reaches approximately 13MW/cm2.

We study the application of a large-core hollow fiber as a platform for displacement sensing. The sensor is assembled by inserting and appropriately moving a single-mode fiber in the empty core of the hollow fiber. Such a construction allows attaining a speckled intensity profile at the hollow fiber output, which is evaluated while one controllably displaces the single-mode fiber in its interior. Our results allow identifying this scheme as a promising means for exploring the multimode characteristics of hollow fibers in sensing contexts.

The thermophoretic efficiency in the modified chemical vapour deposition (MCVD) process has been numerically determined under specified conditions of temperature and velocity field in the silica deposition tube. A CFD code was used to solve a steady-state numerical model of the MCVD process. The cumulative efficiency of $text{SiO}_{2}$ and $text{GeO}_{2}$ deposition was calculated along the tube length, yielding to a maximum value of 42% and 37 % respectivelly.

This paper reports on a micromachined 1D optical scanner using acoustic radiation force. This novel method allows us to actuate the mirror statically without any electrical connection by means of noncontact repulsive force generated by an acoustic radiator placed more than 2 mm far from the mirror. The optical scanning angle of more than 60 degrees was shown by a fabricated 2 mm square mirror in the experiment.

A single stripe multimode laser diode software model has been developed. In addition, a method for measuring the transverse electromagnetic modes (TEM) in the RF spectrum through a frequency beating process was also developed. For supporting the TEM readings, a spectrum analyzer was applied and converted the temporal signals to the frequency domain using the fast Fourier transform (FFT) method.

In this paper, we propose and evaluate a scheme to enhance the performance of optical networks using route segmentation (RS) limited to modulation format maximum range. We have performed this study with an incremental traffic model considering the densely-connected CORONET topology taking the C-band and C+L-bands, with and without the adoption of fiber augmentation (FA). The results show that this strategy can be an interesting way to improve the network performance regarding blocking and bit rates.

By exploiting alternative fabrication processes, electronic and photonic devices can be shrunken and their performance, enhanced. In this work, we study the fabrication of micro and nano structures through thermal scanning probe lithography. With no vacuum requirements, a structure with a minimum dimension of, approximately, 100nm was successfully built, in 17 minutes. Aiming at high performance electronic applications, the structure was coated with a 30nm gold film, and then electric characterized according to its foil resistivity.
