Experimental transmission of a HDMI signal through a photonic link at 1550 nm is successfully demonstrated. The proposed experimental set up is based on external modulation. The HDMI signal is generated by a Raspberry Pi Model B in order to modulate an optical signal. The intensity modulation process is carried out by using a Mach-Zehnder Modulator. The resulting signal is transmitted over 30 km of optical fiber and with the direct detection principle the information is recovered and visualized on a TV screen.

In this work, we introduce a novel design of a gold nanoantenna array. The nanoantenna consists of two elliptical patches. A vertical oval coincides with the minor axis of the horizontal oval. An elliptical aperture etched out from the horizontal one resulting in our Chand-Bali shaped nanoantenna. The geometrical dimensions are properly selected such that two symmetrical small gaps are created. The electric field intensity has a significant enhancement in these two gaps at the same resonance frequency within the near-infrared (NIR) regime for both orthogonal polarizations. The new design offers an improved performance for IR detection and harvesting applications.

We present a method for characterization of thin-film eletro-or magneto-optic materials. Our tool is based on resolving the electric and magnetic field distributions in the near field of a split ring resonator (SRR) designed for the terahertz frequency range. Here, we experimentally validate our simulations by near-field THz imaging of a SRR directly patterned in contact with a thin-film lithium niobate crystal.

Flexibility of COMSOL multiphysics simulation tool makes it possible to estimate the behavior of the Fiber Bragg Grating (FBG) moisture sensor, analyzes mechanical deformation of FBG exposed to hygroscopic polymers and ultimately evaluate electric field strength of propagating light in FBG as a function of geometry deformation. The 2D Moisture sensor model includes Solid Mechanics interface of the Structural Mechanics Module to analyze the deformation of FBG and Electromagnetic Waves interface of Wave Optic Module to analyze wave propagation in the FBG. Light propagation and reflecting wavelength are simulated based on Snell's and Fresnel's laws and none of the Brag equations and expressions is predefined in the model.

An integrated biosensing platform exploiting the properties of Bloch surface waves on all-dielectric thin film stacks is described. It combines label-free sensing based on angular resonance tracking with surface wave enhanced fluorescence excitation and detection. Detailed design considerations reveal a system with defined attenuation to improve resolution limits in both modes.

Three-dimensional (3D) bio-printing has emerged as one of the most influential applications of printing technologies, aiming to address the increased demand for living constructs with long term mechanical and biological stability suitable for transplantation and drug screening applications [1]. Currently, an open challenge in the laser bioprinting field is the fabrication of living constructs of biologically relevant size (∼cm3) with micrometric resolution, i.e., multiscale printing. The paper proposes a novel laser-assisted method that enables multiscale printing of 3D constructs. The method is inspired by studies in the field of laser-assisted drug injection [2]. We will discuss the bio-printing principle, involving a sequence of mechanisms (Figure 1): i) nanosecond (ns) pulsed laser (τ= 6 ns, λ=532 nm) interaction with liquid, ii) cavitation, iii) bubble dynamics, iv) fluid structure interaction, and v) jet dynamics. We used a multiphysics simulation software (COMSOL) to numerically simulate the involved mechanisms. To calculate laser-induced bubble dynamics in a closed chamber, we solved the Rayleigh–Plesset differential equation coupled to a modified Tait equation of state, which accounts for the pressure increase in the chamber because of the laser-induced bubble expansion. We considered 20% conversion of the laser pulse energy to bubble energy, which is a value well documented in the literature [3]. We applied the calculated spatiotemporal dynamics of the bubble boundary as a moving wall to calculate fluid-membrane interaction and the resulting membrane velocity. The membrane velocity profile was then applied to a two-phase flow model to simulate the bio-ink ejection dynamics. We will present the dependence of the jet-dynamics on various key experimental conditions, including liquid rheological properties (dynamic viscosity: 0.89-26.85 mPa·s, density: 996.89-1190.4 kg/m3, laser energy: 5-500J). Finally, we will present an optimization study aiming to reproducible and controllable printing of bio-ink drops with the following characteristics: ejection velocity 5-50 m/s, volume 0.05-30 nL, at the kHz repetition rate regime. Our results demonstrate reliable high-resolution bio-printing for an extended bio-ink viscosity range, representing a model bio-ink that is currently impossible to print using a single conventional bio-printing technology.
