In this work, we propose electrical and thermal control over a horizontal slot waveguide. The proposed device takes advantage of the thermally dependent transition phases of Vanadium Dioxide (VO2), and a high r33 electro-optic polymer called BAY1, which is responsible for the electrical control. We demonstrated a transitioning waveguide which can be used in different applications ranging from phase shifting to plasmonic waveguide feeding by engineering the effective index and mode distribution. Additionally, we report a band gap in our modal analysis that can be engineered without using periodical segmentation, rendering our discovery a useful bicontrollable metawaveguide.

Modern society, increasingly concerned about all the environmental impacts related to the production and use of petroleum-derived fuels, has sought alternative solutions to mitigate these impacts. From this context, ethanol produced from plants such as sugarcane is an important alternative to petroleum-derived fuels and research on production improvement, quality control and other related topics are common in the literature. This work proposes a device based on D-shaped plastic optical fiber to measure the water content mixed into ethanol. This measure is an important quality parameter to guide production and a common way to evaluate any possible adulteration.

The evolution of optical networks, with a focus on supporting next-generation connectivity solutions, is driving the development of technological solutions aimed at reducing capital and operational expenditures and energy consumption while increasing capacity, reach, and information security in optical transmissions. Within this context, this paper addresses recent developments and trends in coherent systems, optical amplification, integrated photonics, software-defined networking, and the use of quantum-based cryptography, which are highlighted across various scenarios, including transport, data center interconnects, access, and mobile xHaul.

In this work, we propose an optical OFDM system using phase modulation followed by optical filtering and direct detection. A fiber Bragg grating is used as an optical filter for phase to amplitude conversion. The performance of the proposed system is investigated for both 16 QAM- and 64 QAM-OFDM signals considering different numbers of training signals for frequency-domain channel estimation. With adequate choice of the training sequence length, BER results below 10−4 are reported for the 16 QAM based signal.

The paper presents some results of the noise spectral interferometry (SI) for precise distance measurements in sub-THz Infra-Red and optical bands using low-coherence optical sources beyond their coherence zone. It is shown that when the path difference in Michelson interferometer exceeds the coherence length of the light-emitting diode radiation, the pattern of interference in spectral domain enables to perform absolute measurements of micro- and nano- distances due to its dependence on both time delay and relative phase of the signals.

A silicon (110) on-chip in-plane Fabry-Perot in-terferometer (FPI) with fiber grooves and polymer reservoirs is fabricated through a single anisotropic wet etching process, resulting in high verticality and low roughness. The FPI exhibits high finesse and Q factors and is functionalized with polymers to enable temperature and gas sensing.

Here we report the characterization of the photoelastic dispersion coefficient using digital holography with two distinct reconstruction methods: one based on the Fresnel method and the other utilizing convolutional neural networks (CNN). The CNN was trained with reconstruction from the Fresnel method and was able to provide reconstructions with an average Mean Squared Error of 0.006.

Quantitative biospeckJe measurements in tomatoes at different ripening stages are reported. The biological activity was calculated with a correlation method using few seconds videos recorded with a low-cost, lensless webcam. 543 and 633 nm lasers were used as light sources similar or complementary to the tomato color. The webcam captures videos at different angles, close or away from the quasi-specular reflection. A new metric (ratio of the biospeckJe activity at two wavelengths) was proposed, allowing for differentiating biological samples at different stages.

This work presents the development of polymer optical fiber (POF) sensors for hydrogen sulfide $(mathrm{H}_{2}mathrm{S})$ detection, coated with varying numbers of metal oxide layers. Four sensors with identical structures were fabricated, and their performance was evaluated when exposed to 200 ppm of $mathrm{H}_{2}mathrm{S}$. Increasing the number of $text{Fe}3mathrm{O}_{4}$ layers led to a sensitivity enhancement, up to 8 times greater with 21 layers compared to 3 layers. However, sensitivity decreased with more than 21 layers. These findings highlight the importance of optimizing the number of layers to achieve the best performance of an $mathrm{H}_{2}mathrm{S}$ sensor.

An optical encoding model based on the coher-ent superposition of two Laguerre-Gaussian modes carrying orbital angular momentum is presented using Machine Learning detection method. In the encoding process, the intensity profile for the encoded data is generated based on selection of $p$ and $ell$ indices, while the decoding process is performed using support vector machine algorithm. Different encoding systems are designed and tested via simulations to verify the robustness of the proposed optical encoding model, finding a BER = 10–9 for 10.2 dB of signal-to-noise ratio in the best of the case.
