The green flash is a rare, brief optical event of green, yellow, and sometimes blue that colors the horizon, occurring at ...

Laser frequency combs are light sources that produce evenly spaced, sharp lines across the spectrum, resembling the teeth of ...

Four-dimensional optics is a research area investigating ... Dr. Mirmoosa adds, "In our paper, we did not take into account ...

Sumitomo Electric sets “new records of low attenuation in low spatial mode dispersion transmission”. Cross-section of the newly-developed coupled multi-core fiber. Sumitomo Electric Industries has ...

The physical characteristics of optical fibers cause some of these wavelengths to travel faster or slower than others (Figure 1). This effect, called chromatic dispersion, can cause serious problems ...

Similarly, the normal dispersion of ULL means light pulses spread ... Vahala says "a comb is like a Swiss army knife for optics. It has many different functions, and that's why it's such a ...

The amount of dispersion depends on the type of fiber, the fiber length and the nature of the optical signal. The more dispersion, the more difficult it is to distinguish between adjacent pulses.
