TRR 142 - Compact high performance photon pair source using ultrafast hybrid modulators based on CMOS and LNOI (C11*)


The project aims to study and demonstrate miniaturized sources of decorrelated photon pairs with high repetition rate. The goal will be achieved by jointly integrating high-bandwidth electro-optic modulators, and a specifically tailored parametric down-conversion (PDC) section, both in a lithium-niobate-on-insulator (LNOI) platform. To obtain decorrelated states the PDC will be pumped with ultrabroadband optical pulses with tailored pulse shapes, tunable bandwidth, and repetition rate generated by means of a novel optical frequency comb synthesis technique. Ultrafast electronics will be integrated in a CMOS chip. Using LNOI and CMOS chips an ultra-compact photon pair source will be demonstrated.
