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

Optical frequency combs technology has become a core technology in information systems over last decade. Recently, UCLA ...

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 ...

Different methods are used for chromatic dispersion and polarization mode dispersion. An optical amplifier similar to an EDFA, but derives a higher gain through a small waveguide rather than ...

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 ...

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.

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 ...

At least until now. Before we come to the latest and greatest, let us discuss how current fiber optic technology sucks. Let's start with something called dispersion. Every material has a ...
