论文简介
A novel optical theoretical model of the Love wave within thin films covered with a
semi-infinite media is derived in details, and further excellent slow light and stored light
phenomena in a thin film are found for the first time. Based on this propagation model and
the optical Love wave theory, the dispersion relation and the group velocity expression are
both obtained exactly, then the mechanism of slow light and stored light phenomena is put
forward, and the influences of the light frequency, the thickness of the thin film, the permittivity
ratio between the thin film and the semi-infinite media, and their refractive indexes
on the group velocity are analyzed. Due to the semi-infinite media, we obtain the excellent
optical phenomena of the Love wave that are caused by both the thin film structure and
boundary conditions, and when the semi-infinite media is vacuum, the Love Wave model
will degenerate into thin films slow light. The slow light and stored light phenomena in a
thin film could have potential applications in the data storage field.
