Abstract
We prove the existence of gap solitons supported by a photonic lattice embedded in an unbiased photovoltaic photorefractive crystal for the first time. Double-hump and multi-hump gap solitons are found to exist in the first finite band gap but no gap solitons are found to exist in the second finite band gap.
