Abstract

Unlike a planar lightwave, a tightly focused light beam has longitudinal components of the electric field (LCEF) that are polarized along the propagation direction. This article reviews the past and present status of theoretical and experimental studies on the LCEF. By pointing out that the LCEF is an essential constituent element of the dressed photon (DP), the future outlook of these studies for advancing DP science and its applications is discussed.
