Abstract
The interplay of nonlinearity and dispersive properties of nanostructured optical materials offers a versatile platform for the realization of a multitude of interesting fundamental effects and useful applications, ranging from spatio-temporal dynamics, nonlinear pattern formation, efficient frequency generation, all-optical signal processing, to generation of nonclassical photon states. Here we provide a systematic overview of recent achievements based on our ability to nanostructure lithium niobate on the nanoscale with a unprecedented precision. Due to its high second order nonlinear coefficients and large transparency window lithium niobate is known for years as an excellent material for nonlinear optics. While these favourable properties have been extensively used already for classical integrated optics, nanostructures, which allow the realization of a much broader range of dispersive optical properties, are much harder to fabricate. Despite the complications of nano-processing of this material, we have developed several technique based on ion-beam enhanced etching, which allow us to realize micro- and nanostructures over a broad geometrical parameter range, well adapted to the control of light on the nanoscale [1]. Structures with precisely defined geometries are formed using spatially structured irradiation with swift heavy ions, which locally destroys the crystal structure, to control subsequent wet etching processes. With this fabrication technique we are able to manufacture different types of resonant nanostructures.
