As of 2024, Saudi Arabia's GDP per capita has surpassed all other GCC countries except Qatar and the United Arab Emirates. Saudi Arabia's GDP per capita is estimated to be approximately $33,040 in nominal terms, ranking it 35th globally, and $70,333 in purchasing power parity (PPP) terms, ranking it as the 15th highest in the world [[15]]
Polar Electro Oy (commonly known as Polar) is a Finnish manufacturer of sports training computers, particularly known for developing the world's first wireless heart rate monitor. [ 1 ] The company is based in Kempele , Finland and was founded in 1977.

watt per square metre per hertz W⋅m −2 ⋅Hz −1: M⋅T −2: Radiosity of a surface per unit frequency or wavelength. The latter is commonly measured in W⋅m −2 ⋅nm −1. This is sometimes also confusingly called "spectral intensity". J e,λ [nb 7] watt per square metre, per metre W/m 3: M⋅L −1 ⋅T −3: Radiant exitance: M e ...
A PMD compensation system is a device which uses a polarization controller to compensate for PMD in fibers.Essentially, one splits the output of the fiber into two principal polarizations (usually those with dτ dω = 0, i.e. no first-order variation of time-delay with frequency), and applies a differential delay to re-synchronize them.
resulting in generation of waves with frequencies given by ω = ±ω 1 ± ω 2 ± ω 3 in addition to third-harmonic generation waves with ω = 3ω 1, 3ω 2, 3ω 3. As above, the phase-matching condition determines which of these waves is the dominant. By choosing conditions such that ω = ω 1 + ω 2 − ω 3 and k = k 1 + k 2 − k 3, this ...
In October 2022, during an experiment held at the Technical University of Denmark in Copenhagen, a photonic chip transmitted 1.84 petabits per second of data over a fibre-optic cable more than 7.9 kilometres long. First, the data stream was split into 37 sections, each of which was sent down a separate core of the fibre-optic cable.
Within optics, dispersion is a property of telecommunication signals along transmission lines (such as microwaves in coaxial cable) or the pulses of light in optical fiber. In optics, one important and familiar consequence of dispersion is the change in the angle of refraction of different colors of light, [ 2 ] as seen in the spectrum produced ...
