Integrated optics

The integration of several functional elements on one optical chip is of high importance for many applications, e.g. optical signal processing. Using lithium niobate, a material with large transparency range as well as high nonlinear and electro-optic coefficients, we develop technologies and devices that enable the use of active and passice photonic elements on one chip. Based on recently established nanofabrication technology for nanostructures in lithium niobate, we aim to design, manufacture and experimentally test sources for photon pairs, linear optical manipulation circuits, active elements as lasers and modulators, and complex functional quantum devices on the lithium niobate platform.
