It was shown that the power attenuation parameter [alpha] in a multilayer structure is a function of effective values of dielectric properties which in turn are functions of [epsilon]', [sigma] and the thickness of all layers.
Trend of power attenuation in the multilayer model of abdominal medium.
FiberStore's Variable Optical Attenuator dies have been designed to fit most packaging technologies available on the market and in closed loop mode exhibit superior optical power attenuation
proportional to the signal power attenuation
and, hence, to the carrier-to-noise ratio, which could also lead to the increase in the error rates.
Moreover, the power confinement factor and power attenuation were investigated for this waveguide structure.
In Figure 6, we plotted the power attenuation (the imaginary part of (16)) versus frequency for different slab thicknesses.
System software controls all laser parameters such as power attenuation
and ablation spot size.
It provides stable laser sources and accurate power meter for physical layer testing and qualifying the power attenuation
in the fiber link or optical components.
To obtain the power attenuation
rate, the attenuation constant of the composite electrical field, E = [square root of [E.sup.2.sub.x] + [E.sup.2.sub.y] + [E.sup.2.sub.z], must be calculated.
