Abstract :
We demonstrate zero phase delay and deterministically tunable zero-n bandgaps in path-averaged zero-index photonic crystal superlattices. Phase differences are measured with integrated Mach-Zehnder interferometers and all measurements agree well with theoretical analysis and simulations.
