The performance of many optical devices based on frequency conversion critically depends on spatial modulation of the nonlinear optical response of materials. This modulation ensures efficient energy exchange between optical waves at different frequencies via quasi-phase matching1. In general, quasi-phase-matching structures, also known as nonlinear photonic crystals2,3,4, offer a variety of properties and functionalities that cannot be obtained in uniform nonlinear crystals5,6,7,8,9. So far,...[Show more]
