“…The deviation of the end point from the unperturbed orbit yields a column of the operator M. This method bears some similarity to the one developed in ref. 41 but here over a period and not a single time step. Owing to the large size M ð Þ $ 10 5 , the eigenvalues and eigenvectors cannot be calculated from a complete decomposition using for instance the QR method 40 .…”

Optical localized states are usually defined as self-localized bistable packets of light, which exist as independently controllable optical intensity pulses either in the longitudinal or transverse dimension of nonlinear optical systems. Here we demonstrate experimentally and analytically the existence of longitudinal localized states that exist fundamentally in the phase of laser light. These robust and versatile phase bits can be individually nucleated and canceled in an injection-locked semiconductor laser operated in a neuron-like excitable regime and submitted to delayed feedback. The demonstration of their control opens the way to their use as phase information units in next-generation coherent communication systems. We analyse our observations in terms of a generic model, which confirms the topological nature of the phase bits and discloses their formal but profound analogy with Sine-Gordon solitons.

“…Taking one point of the periodic orbit, we insert a small perturbation in all the degrees of freedom as represented by the mesh points in the delay time and let the system evolve over one period. The deviation of the end point from the unperturbed orbit yields a column of the operator M. This method bears some similarity to the one developed in [40] but here over a period and not a single time step. Due to the large size dim (M) ∼ 10 5 , the eigenvalues and eigenvectors can not be calculated from a complete decomposition using for instance the QR method [39].…”
