Line-scan rates of mechanical scanners are in general limited to <100 kHz for scan mirror apertures of up to 1 mm. We present work to increase the line-scan rate of a MEMS micromirror beyond this through a scan multiplication unit consisting of a mirror, a cylindrical lens, and a 3D-printed cylindrical microlens array with 1 mm pitch and 2.5 mm effective focal length. Scan rates of up to 635 kHz at the scan line centre are demonstrated with seven array lenslets, with the compact multiplier having the potential to achieve over 1 MHz line-scan rate using higher element numbers.

Here we applied ATR-FTIR spectroscopy combined with computational modeling based on 3D-discriminant analysis (3D-PCA-QDA). Our results present an exceptional performance of 3D-discriminant algorithms to diagnose BCC skin cancer, indicating the accuracy up to 99%.

The impact of probabilistic shaping in unrepeatered optical communication links operating in the linear, quasi-linear, and nonlinear regimes is investigated. System performance is evaluated considering both uniform and Maxwell-Boltzmann distributions at three different representative launch power levels. Results show shaping-induced gains for all investigated scenarios.

We report the realization of temperature sensing measurements using a water-filled hollow-core photonic crystal fiber. The operation of the sensor relies on the thermo-optic effect-mediated spectral shifts of the fiber transmission bands due to temperature variations. The characterization of our device allowed us to estimate a sensitivity of $(0.42pm 0.04)text{nm}/^{circ}mathrm{C}$ and to identify the studied platform as a valid path for the development of fiber-based temperature sensors.

Random lasers are easier and cheaper to manufacture than regular ones, being made of several materials such as polymers, powders or dyes. Glass random lasers have been rarely studied due to their inhomogeneous broadened emission and low damage threshold. Here, we study Nd3+doped Te02-ZnO-Al203 glasses with different concentrations of rare-earth doping (4 wt.%, 8 wt.% and 16 wt.%). Emission intensity per pump fluence and fluorescence decay time measurements showed the potential of these glasses for random laser applications in the near-infrared region.

This work reports the fabrication of agar ball lenses, an biodegradable, edible, and renewable material. Pouring melted agar-glycerol-water solutions into vegetable oil produces transparent spheres whose refractive index and diameter change with glycerol concentration and agitation speed. Results confirm the agar lens feasibility for imaging suggesting possible applications.

We report a record optical-to-optical efficiency of 43% and a slope efficiency of 48% for a Nd: YLF laser emitting at 1314 nm. The crystal was side-pumped by a VBG-equipped diode emitting at 797 mn, with a peak power of 1545 W. We also report simultaneous dual-wavelength emission, at 1313 nm and 1047 nm.

A subwavelength perforated structure designed for a maximum absorption-to-mass ratio has been utilized to construct an uncooled infrared $(lambda sim 8-12 mu mathrm{m})$ thermal detector operating in air with a noise equivalent temperature difference (NETD) of $23 text{mK}$ and detectivity of $1.1times 10^{9}text{cm}sqrt{mathrm{H}mathrm{z}}/mathrm{W}$ while time constant is 1.5 ms. With a fill factor of $sim 27%$, the detector shows an average absorption per unit mass of $sim 6.8times 10^{12}text{kg}^{-1}$ over the long-wave infrared regime. Mach-Zehnder interferometry has been used for optical readout of the detector.

Erbium-doped fiber amplifiers performance, especially designed with high doping concentration to operate at the optical L-band, were experimentally characterized in terms of gain, ripple, and noise figure power masks as a function of both pump power and signal input power. The results indicate the possibility of achieving an optical gain of around 15 dB with a nearly equalized output, using doped fibers with only 25 m of length.
