We demonstrate that coupled waveguides systems can be operated in the so called non-
adiabatic regime. In this regime, light can undergo transition between different steady states,
also called photonic bands. This approach contrasts with previous strategies in integrated
photonics that rely exclusively on the adiabatic control of the flow of light. We show that the
constraint for adiabaticity being lifted, light can now be manipulated optimally.
