A University of Ottawa team has developed a new way to protect free-space quantum key distribution (QKD) from atmospheric turbulence, one of the main causes of distortion and errors when sending ...

The fragility and laws of quantum physics generally make the characterization of quantum systems time‑consuming. Furthermore, ...

A nanophotonic diffractive network performs morphological image processing, including dilation and erosion, purely through light propagation.

Engineering researchers report that they developed a new, efficient way to modulate and enhance an important type of nonlinear optical process: optical second harmonic generation -- where two input ...

For thin film optical coatings, most critical production challenges appear in the first half of the manufacturing cycle, particularly in coating deposition methodologies. As explained by Ron Willey, ...

For decades, optical inspection has been the primary method for process control in fabs. However, the move to multi-level ...

Researchers created an inverse design codebase called SPINS that can help researchers explore different design methodologies to find fabricable optical and nanophotonic structures. Stanford University ...

Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical fiber at visible wavelengths. This accomplishment paves the way for a new ...
