Photonic analog of Zitterbewegung in binary waveguide arrays
Photonic analog of Zitterbewegung in binary waveguide arrays
An optical analogue of Zitterbewegung (ZB), i.e. of the trembling motion of Dirac electrons caused by the interference between positive and negative energy states, is proposed for spatial beam propagation in binary waveguide arrays. In this optical system ZB is simply observable as a quiver spatial oscillatory motion of the …
