optical pulse

optical pulse

[′äp·tə·kəl ′pəls]
(optics)
A short flash of light, used to isolate moments of time; pulses as short as 15 femtoseconds have been generated with laser and pulse compression techniques.

Key to the technique is highly nonlinear optical fiber that acts as a mixer between the optical signal and a very narrow optical pulse.
As a consequence, the five hundred and ninety handpainted dots subtly shift and change from canvas to canvas, only adding to the optical pulse of this field of paintings that are almost exactly the same but utterly unique.
In "ES Spiral Trim Maze" (2013) a coil of white paint elicits a gentle optical pulse as it directs the eye back and forth across a loose arrangement of differently sized and colored pieces of wood.
On the other hand, a few tens bits of a few Gbps optical pulse signal have been variably delayed using a double absorption resonance in hot Cs vapor [6].

As a result, the bit rate of the optical pulse increases.
In order to operate a DWDM-PON system with a sufficiently low BER and minimize the performance degradation caused by optical pulse distortion and broadening, dispersion compensation is needed [6, 9].
NLSE supports both linear and nonlinear effects, suitable for describing optical pulse propagation inside single-mode fiber.
After completing the first scan with a short-duration optical pulse, a longer-duration pulse is selected to provide additional optical power to test further along the fiber.
Optical pulse propagation in whispering-gallery modes of liquid spheres has been studied in the time domain.
Furthermore, the fracturing of a rock sometimes produces not only the optical pulse but also "a curious radio emission" with frequencies ranging from about 900 to 5,000 hertz, Zito says.
