The scientific and practical issues of the development of core mixtures for foundry, based on phosphate binding materials, are considered. The binder presented in this article differ from those previously known by the fa...

AI/ML compute clusters are driving unprecedented bandwidth demands at the package boundary, motivating co-packaged integrated photonics closely co-located with the compute unit. We present a scalable silicon-photonics tr...

Optical pulses are essential as information carriers, for driving nonlinear light sources, imaging, the study of attosecond science and 3D printing. In many applications, short pulses are needed. For example, the resolut...

The technology of synthesis of inorganic binder material based on sodium tripolyphosphate Na5P3O10 and orthophosphoric acid has been developed. The sequence of physicochemical transformations in this system, as well as t...

Electro-optic modulators provide a key function in optical transceivers and increasingly in photonic programmable application-specific integrated circuits (ASICs) for machine learning and signal processing. However, both...

Electro-optic signal modulation provides a key functionality in modern technology and information networks. Photonic integration has not only enabled miniaturizing photonic components, but also provided performance impro...

We present a new instrument composed of a large number of sub-electron noise SkipperCCDs operated with a two stage analog multiplexed readout scheme suitable for scaling to thousands of channels. New, thick, 1.35 Mpix se...

Urban analysis covers the period from the construction of the first blast furnace in the Konecki estates – 1738/39 until 1967 when Stąporków gained the city rights. The industrial development of the village is connec...

Photonic integrated circuits (PICs) are an ideal platform for chip-scale computation and communication. To date, the integration density remains an outstanding problem that limits the further development of PIC-based pho...

The article presents the study results of new inorganic binders and the physicochemical processes of their formation. The main purpose of the created materials is to make molds and cores for foundry production. Creating...

Optical modulators are vital for many applications, including telecommunication, data communication, optical computing, and microwave photonic links. A compact modulator with low voltage drive requirement, low power, hig...

Rapid progress has been made in recent years repurposing CMOS fabrication tools to build complex photonic circuits. As the field of silicon photonics becomes more mature, foundry processes will be an essential piece of t...

Silicon nitride (SiN) is a key material for quantum photonics due to its wide transparency window, high refractive index, low optical losses, and semiconductor foundry compatibility. We study the formation of single-phot...

Silicon photonics has gained great success mainly due to the promise of realizing compact devices in high volume through the low-cost foundry model. It is burgeoning from laboratory research into commercial production en...

A compact spectrometer on silicon is proposed and demonstrated with an ultrahigh resolution. It consists of a thermally-tunable ultra-high-Q resonator aiming at ultrahigh resolution and an array of wideband resonators fo...

Este artigo tem por objetivo analisar a política fundiária executada pelo governo Olívio Dutra, no estado do Rio Grande do Sul -Brasil, levando-se em consideração as suas diretrizes, a dinâmica da luta política tr...

La evidencia arqueológica procedente del sector sur del valle de Yocavil indica que los artesanos prehispánicos utilizaron, entre otros métodos, la fundición por cera perdida en la manufactura de objetos metálicos. ...

"En la industria de fundición, la mayor preocupación en materia ambiental es la disposición de las arenas descartadas de fundición (ADFs), debido a que en la mayoría de los casos son dispuestas como material de rell...
