The rapid advancement of modern technology has led to a steep rise in global energy demand, posing serious challenges related to climate change and the geopolitical complexities of energy sourcing. In this context, modulators and optical amplifiers have be ...

Spin states in semiconductors provide exceptionally stable and noise-resistant environments for qubits, positioning them as optimal candidates for reliable quantum computing technologies. The proposal to use nuclear and electronic spins of donor atoms in s ...

The unique physical properties of two-dimensional materials have attracted substantial research efforts in the last twenty years. The possibility of stacking layered materials in freely-configurable stacks, called van der Waals heterostructures, has enable ...

Dielectric elastomer actuators (DEAs) are a recent type of smart materials that show impressive performances as soft actuators, making them a promising technology for the development of implantable artificial muscles and soft robotic devices. Notably, they ...

We experimentally study the spectral lasing response of on-chip InP network random lasers under illumination of different input image shapes. Deep-learning models have become increasingly omipresent throughout society. However, they are blighted by exponen ...

We present an algorithm to arbitrarily engineer the dispersion of photonic-crystal Fabry-Pérot resonators via the accurate design of chirped reflectors, opening avenues to exotic dispersion profiles, dispersive-wave engineering and near-zero-dispersion sol ...

We demonstrate hybrid integration of an RSOA with an extended-distributed Bragg reflector (E-DBR) laser cavity implemented on a Si3N4 chip with monolithically integrated piezoactuators. The laser exhibits intrinsic linewidth of 4 Hz with laser frequency tu ...

This paper presents a new method and structure to suppress unwanted interference in conventional Global Positioning System (GPS) applications. In contrast to traditional antennas that usually utilize high-impedance structures with limited enhancement or th ...

This article presents the design, implementation, and first data of a uniquely flexible, multi-channel, frequency comb Doppler backscattering diagnostic recently made operational in the ASDEX-Upgrade tokamak [A. Gruber and O. Gruber, Fusion Sci. Technol. 4 ...

Laser powder bed fusion (L-PBF) has emerged as an additive manufacturing technique that offers unprecedented design freedom. Besides being capable of producing complex and near net shape objects, L-PBF can impact tremendously the engineering materials comm ...

Space-time (ST) wave packets have gained much interest due to their dynamic optical properties. Such wave packets can be generated by synthesizing frequency comb lines, each having multiple complex-weighted spatial modes, to carry dynamically changing orbi ...

Light matter interactions such as extinction, reflection, and transmission can be described by classical optics. Dur-ing the past decades, research focused on a novel resonant extinction type called plasmonics that allows for en-hancement of both types of ...

The science and engineering of two-dimensional materials (2DMs), in particular, of 2D semiconductors, is advancing at a thriving pace. It is well known that these delicate few-atoms thick materials can be damaged during the processing toward their integrat ...
