Abstract

We design, fabricate, and characterise a balanced directional coupler in lithium niobate on insulator (LNOI) and use it to demonstrate Hong-Ou-Mandel interference of telecom photons with a raw visibility of (93.5±0.7) %.

Demonstration of Hong-Ou-Mandel interference in an LNOI directional coupler

Silia Babel, Laura Bollmers, Marcello Massaro +9 more

Interference between single photons is key for many quantum optics experiments and applications in quantum technologies, such as quantum communication or computation. It is advantageous to operate the systems at telecommunication wavelengths and to integrate the setups for these applications in order to improve stability, compactness and scalability. A new promising material platform for integrated quantum optics is lithium niobate on insulator (LNOI). Here, we realise Hong-Ou-Mandel (HOM) interference between telecom photons from an engineered parametric down-conversion source in an LNOI directional coupler. The coupler has been designed and fabricated in house and provides close to perfect balanced beam splitting. We obtain a raw HOM visibility of (93.5 ± 0.7) %, limited mainly by the source performance and in good agreement with off-chip measurements. This lays the foundation for more sophisticated quantum experiments in LNOI.

We describe the first electrically-driven single-photon source which can demonstrate Hong-Ou-Mandel type interference. Experiments were performed under both pulsed and CW excitation, and we discuss the factors limiting visibility in both cases.
