Experimental control of pattern formation by photonic lattices

Marsal, N.; Wolfersberger, D.; Sciamanna, M.; Montemezzani, G.; Neshev, D. N.


We study the control of modulational instability and pattern formation in a nonlinear dissipative feedback system with a periodic modulation of the material refractive index. We use a one-dimensional photonic lattice in a single-mirror feedback configuration and identify three mechanisms for pattern control: bandgap suppression of instability modes, periodicity induced pattern modes, and orientational pattern control.
