TTR 142 - Integrated SU(1,1) interferometers (C02)
The primary goal of this project phase is to develop LiNbO3 based integrated circuits for quantum metrology applications. Based on LiNbO3-tool box components developed in the first phase of the project, we plan to develop integrated non-linear SU(1,1) interferometers in different configurations. Such interferometers are a very promising tool for ...
