While single-mode semiconductor lasers have various advantages, one disadvantage is their great sensitivity to optical feedback. Even small amounts of reflected light can have a destabilizing effect, ...

Sandra Stevens made the transition three years ago from working in retail to becoming a full-time construction estimator, in a field that is facing an employment shortage.

In many biomedical applications, broad full-color emission is important, especially for wavelengths below 450 nm, which are difficult to cover via supercontinuum generation. Single-crystalline-core ...

We present the fabrication of a polarizing, endlessly single-mode microstructured fiber with high polarization-dependent loss. The fiber was fabricated by the stack-and-draw method. The resulting ...

Ukraine is fighting against Rusisa's advanced fiber-optic drones that can't be jammed, and soliders have to use old-fashioned weaponry to stop them.

This work proposes a novel large mode area fiber with multi-layer holes of 2.0 μm based on electromagnetic field theory and finite element analysis. Modifying the structure parameters can reduce the ...
