Nonlinear light propagation in rotating waveguide arrays

We experimentally and theoretically study nonlinear light propagation in a rotating waveguide array. We show that noninertial effects can lead to mode conversion, enhanced transport, and vector (gap) soliton formation. Experimentally, we directly observe these dynamics, both within and between bands, by recording intensity in position space and power spectra in momentum space. The results are fundamental to all rotating nonlinear lattices and hold potential for a variety of twisted photonic devices.
