Fig. 1. (a) Schematic of the 1x2 optical switch element based on the Ln-Si3N4 hybrid waveguide. (b) Missalignment tolerance of the evanescent coupler in the Y direction. (c) Effective index of the ...

Opaque materials can transmit light when excited by a high-intensity laser beam. This process, known as optical bleaching, induces a nonlinear effect that temporarily alters the properties of a ...

Salience Labs, the startup company spun out of silicon photonics research at the University of Oxford in the UK and the University of Münster in Germany, says it has raised another $30 million in a ...

A keyboard might be just another input device for many, but a highly personal and valued part of their PC setup for others. While many parts come together to determine how good a keyboard sounds and ...

Researchers have developed a new type of optical memory called a programmable photonic latch that is fast and scalable, enabling temporary data storage in optical processing systems and offering a ...
