The Excitation of Surface Plasmon-Polaritons in the Process of Raman Interaction
The enhancement of surface plasmon polariton (SPP) gain and propagation length at optical frequencies on the interface between a metal film and a medium with Raman gain, in the presence of a coherent control field, is theoretically investigated. It is shown that the Raman interaction between the SPP excitation field and the control field can provide gain sufficient for lossless SPP propagation. This interaction reduces the requirement for the SPP excitation field. It is shown that a significant increase of the propagation length can be achieved in the case of lossy propagation. By varying the intensity or frequency of the control field it is possible to control the SPP. Optical control of the dynamics of SPP propagation by means of an external coherent field in the Raman interaction process holds promise for quantum control in the field of photonics.
期刊介绍：
Annalen der Physik (AdP) is one of the world''s most renowned physics journals with an over 225 years'' tradition of excellence. Based on the fame of seminal papers by Einstein, Planck and many others, the journal is now tuned towards today''s most exciting findings including the annual Nobel Lectures. AdP comprises all areas of physics, with particular emphasis on important, significant and highly relevant results. Topics range from fundamental research to forefront applications including dynamic and interdisciplinary fields. The journal covers theory, simulation and experiment, e.g., but not exclusively, in condensed matter, quantum physics, photonics, materials physics, high energy, gravitation and astrophysics. It welcomes Rapid Research Letters, Original Papers, Review and Feature Articles.
