FTIR结构中隧穿光子的横向位移

Lateal Shift of Tunneling Photons in Frustrated-total-internal-reflection Structure

讨论了在二维光学受阻全内反射（ＦＦＩＲ）结构中隧穿光子的横向位移问题。在简要地回顾了位相时间、特别是与其关联的横向位移在不透明极限下的饱和性质之后，给出了与能量转移速度相关的隧穿时间及相应的横向位移。该隧穿时间是不超光速的，在不透明极限下，相应的横向位移对势垒厚度的依赖关系是超线性的。

The lateral shift problem of tunneling photons in the 2 - dimensional optical frustrated - total - internal- reflection structure is discussed. Firstly, the saturation characteristic of the phase time and its associated lateral shift is reviewed succinctly in the opaque barrier limit. Then a new tunneling time and its associated lateral shift is introduced under the assumption that the tunneling speed is the energy transfer speed in the barrier. the proud tunneling time is subluminal, and its associated lateral shift is super - linearly dependent on the barrier thickness in the opaque limit.
