A bimodal waveguide sensor has a waveguide portion biochemically functionalized to bind to a specific target, allowing interferometric sensing of the target.
A software algorithm based on social learning particle swarm optimization (SL-PSO) simultaneously optimizes source and mask for extreme-ultraviolet (EUV) lithography.
Using a laser with a milliwatts-level output, two linearly coupled microresonators produce a microcomb potentially widely useful in spectroscopy, communications, and other applications...
A single-mode silica fiber has a high-refractive-index rod placed in the cladding that resonates with the core, absorbing light at certain wavelengths.
Accelerating a small chemical specimen to relativistic speeds slows down its “internal clock,” enabling higher temporal resolution for ultrafast studies.
Confirmed by experiment, calculations show how deep light goes into a DBR mirror before it reflects; this is relevant for determining microcavity lengths.
The current missions to Mars are exciting to follow, and show the value of science and photonics as exploration and the search for life on another world put life on Earth in perspective...
