Fig. 4: Centre of intensity xc vs. propagation distance y for resonant excitation at two different angles.
From: Observation of Zitterbewegung in photonic microcavities
Blue points give the experimental data. A red solid line gives the theoretical fit. a Case for excitation of the p-band states, corresponding to the black circle in Fig. 3d. b Case for excitation of the s-band states, corresponding to the red circle in Fig. 3e. The zero of the y-axis is defined as the edge of the lattice where the pump spot is incident
