How to superimpose six light waves without interference — •Koen van Kruining1, Rob Cameron2, and Jörg Götte3 — 1Max Planck Institut für Physik komplexer Systeme, Dresden — 2University of Strathclyde, Glasgow, UK — 3Nanjing university, Nanjing, China
We present a set of superpositions of up to six plane light waves which have a homogeneous electric field strength. For most physical processes, including human eyesight, these superpositions can be considered noninterfering. Because of the homogeneity of the electric field strength effects beyond the electric dipole interaction become noticeable and the lights inhomogeneous helicity can be probed. Among others, our superpositions allow for writing a variety of periodic patterns in liquid crystalline polymers and to make periodic traps for birefringent particles suspended in water.
