Abstract
Apparatuses and methods are provided for an optical frequency converter configured to double or have a carrier frequency of an input optical signal. The input optical signal provided to the optical frequency converter is a higher order mode than a mode of the output optical signal. The optical frequency converter comprises a core, cladding material, and a substrate. The core includes a first core portion of non-linear crystalline material which is non-centrosymmetric, and a second core portion and a third core portion of the non-linear crystalline material each of which is centrosymmetric. The first, the second, and the third core portions are coplanar with and adjacent to the first core portion between the second and the third core portions.
