平面多模波导中光动量的恢复和振荡

Revivals and oscillations of the momentum of light in a planar multimode waveguide

Yuri B. Ovchinnikov, Tilman Pfau

摘要:

研究了单色光以大角度入射多模平面波导时横向动量的演化。我们报告相邻的填充模式的波导和他们的周期性崩溃和复兴之间的跳动所造成的动量振荡。基于这种效应的一种新型干涉仪的条纹间距小到光波长的1/9,实验证明和周期小到光波长的1/1000似乎是可行的。

英文摘要:

The evolution of the transverse momentum of monochromatic light entering a multimode planar waveguide at large angle is investigated. We report on oscillations of the momentum caused by the beatings between the adjacent populated modes of the waveguide and their periodic collapses and revivals. A new type of an interferometer based on this effect with fringe spacing as small as 1/9 of a light wavelength is demonstrated experimentally and periods as small as 1/1000 of a light wavelength seem to be feasible.
