Pulse envelope has smaller propagation velocity than optical carrier - Normal dispersion.
Summary
[edit]
| Description |
English: Pulse envelope has smaller propagation velocity than optical carrier in material with normal dispersion.
- In time delay this shows as larger delay of the envelope as the pulse propagates. - Group delay is larger than phase delay. - Group velocity is smaller than phase velocity. Pulse length dt=14 ps and carrier at 1000 nm. Model and animation was generated with Matlab. |
