A laser-written glass chip shows how fragile quantum signals can be decoded with high stability and low loss, offering a new ...

As quantum computers continue to advance, many of today's encryption systems face the risk of becoming obsolete. A powerful alternative—quantum cryptography—offers security based on the laws of ...

Abstract: A design of buried square core (BSC) waveguide structure for a polymer based directional coupler at third telecommunication window is presented. The optimization of the waveguide dimension, ...

Abstract: We propose and experimentally demonstrate directional couplers with arbitrary coupling ratios using pseudomagnetic fields (PMFs) in silicon photonic crystals at telecommunication wavelengths ...
