ABSTRACT:
Device for performing a parametric process, comprising a substantially periodic photonic crystal structure comprising a plurality of unitary cells each comprisinga first layer having a first refractive index n1and a first length L1,a second layer having a second refractive index n2,with n1different from n2,and a second length L2,a third layer having a third refractive index n3,with n3different from n2,and a third length L3anda fourth layer having a fourth refractive index n4,with n4different from n1and from n3,and a fourth length L4, whereinat least one among the first, the second, the third and the fourth layers has a non-linearity of the χ2or χ3type;at least one of the following conditions is met: a) n1is different from n3; b) n2is different from n4; c) L1is different from L3; d) L2is different from L4;andn1,n2,n3,n4,L1,L2,L3,L4have such values as to perform the parametric process in phase matching conditions.
