group velocity

In light of this finding, scientists have wondered whether single photons travel at the group velocity or the signal velocity.

Evolution of chirp is simulated by computer and chirp as a function of the fiber loss and group-velocity mismatch is analysed.

After some thought, however, we realized it was wrong to rely on the beat pattern as an indicator of group velocity.

We have proved the superluminal group velocity is an unstable natural phenomenon by experiment.

In recent years, researches about the controllable group velocity of light propagation had made many progresses.

In recent years, researches about the controllable group velocity using difference methods arouse great interest among researchers.

The group velocity is the speed at which modulated signals would be transmitted.

The phase velocity and the group velocity of acoustic waves inside sonic crystals have been analyzed and measured.

The superluminal group velocity has already been observed in optics and electricity fields by some researchers.

Then the possibility of larger phase velocity and group velocity than light speed in dispersive medium is discussed.

In addition, the group velocity of the probe laser can be reduced at each transparency window.

The group velocity and the density of states are used to explain the mechanism of high quality factor for the first time.

Meanwhile, the group velocity of the solitons is subluminal.

When the medium density increases (with more atoms), the slow group velocity decreases.

In photonic crystal band gap defect mode, a long group time delay is gained when the group velocity is greatly decreased.

The group velocity delay of P wave was derived by using an improved multi-filtering method.

With any signal you can talk about two speeds called the phase velocity and the group velocity.

In this thesis, the scattering matrix method is used to study the effective group velocity refractive index of 2D finite structure.
