We experimentally demonstrate using data-carrying Gaussian beam to "hide" a weaker data carrying OAM beam. A 50-Gbit/s QPSK data link with Q factor above 4.5 is realized for the weak OAM beam when the power difference between Gaussian and OAM beam is 30-dB.

Traditional display protocols have limitations in terms of fixed refresh-rates, high bandwidth requirements, and control over the display of frames. This paper demonstrates the performance results of an alternative approach utilizing a packetized display protocol architecture incorporating dynamic refresh-rates, high-speed capabilities, to bridge performance gaps.

Sub-unit cells consisting of printed conducting gaps and magneto-static particles to form the foundation of a proposed leaky wave antenna was experimentally evaluated and the results are presented in this paper. However, for initial experimental purposes, vias were used to model the magneto-static responsive particles in the PCB substrate for both the ON and OFF states. Then the S-parameters of an N=10 cascaded (i.e., series connected) sub-unit cell in a microstrip transmission line configuration was presented and it was shown that the propagation characteristics of the interconnected cells can be controlled with magneto-static particle equivalent regions (i.e., vias). Finally, the unit cell designs were compared between two simulation software tools and the results of the printed prototypes.

Non-Hermitian singularities known as exceptional-points (EPs) have been shown to exhibit increased sensitivities but the observation of EPs has so far been limited to wavelength scaled systems subject to diffraction limit. We propose a novel approach to EPs and report their first observation in plasmonics at room temperature. The plasmonic EPs are based on the hybridization of resonances in multilayered plasmonic crystals to reach a critical complex coupling rate between nanoantennas arrays, and, resulting in the simultaneous coalescence of the resonances and loss rates. Because plasmons shrink the wavelength of light to make it compatible with biological relevant substances, enhanced sensing of anti-Immunoglobulin G, the most common antibody found in blood circulation, is observed at attomolar concentration. Our work opens the way to novel class of nanoscale devices, sensors, and imagers based on topological polaritonic effects.

A study of the well-width impact on the AlGaN laser is presented. The laser threshold and optical gain are significantly influenced by the quantum well design. A low threshold of 5 kw/cm2 is achieved in the 3 nm well width due to a reduced QCSE.

We investigate the atmospheric propagation of high power 10μm — picosecond laser pulses over multi-km distances in the atmosphere. We predict that 10μm atmospheric filaments have noteworthy advantages when compared their shorter wavelengths counterparts, which are expected to have important impact in future applications.

We performed a detailed study on the triplet state absorption properties of seven organometallic complexes. The singlet-triplet conversion quantum yield was obtained based on a 6-level electronic model. We observed triplet yields of less than unity, contrary to previous reports for this class of compounds.

Laser diagnostics are essential for time-resolved studies of solid rocket propellant combustion and small explosive detonations. Digital in-line holography (DIH) is a powerful tool for three-dimensional particle tracking in multiphase flows. By combining DIH with complementary diagnostics, particle temperatures and soot/smoke properties can be identified.

A 21-subject pilot study was conducted in which apocrine and eccrine sweat was collected from healthy male (n = 7) and female (n = 14) individuals during aerobic exercise. Sweat from participants was analyzed using a blue tetrazolium reaction to determine cortisol concentration. The study revealed a significant difference between male and female apocrine cortisol concentration (p-value = 0.044), a highly significant difference between birth control (BC) using females and non-birth control using females (p-value = 0.015), as well as a highly significant difference between apocrine and eccrine cortisol concentration (p-value = 0.000044). A positive correlation between cortisol and Kessler 10 scores, protein, simple carbohydrates, fat, and calorie consumption in BC users, as well as a negative correlation between cortisol and simple carbohydrates, fat, and calorie consumption in non-BC users were found. This pilot study revealed a key association between diet and cortisol that may help individuals lower their normal cortisol levels and therefore prevent stress related illnesses.
