C01: Engineered frequency conversion devices

Abstract

In this project, we aim to fabricate integrated frequency conversion devices tailored for spectral-temporal manipulation and detection of quantum light emitted from semiconductor structures. The frequency converters will be developed on a lithium niobate platform and we will target for high-performance plug-and-play devices with fiber pigtailed connectors. Incorporating conventional time-domain pulse characterization techniques such as streak cameras, we will show an unprecidented detection efficiency for sub-picosecond pulsed quantum light at the near-infrared spectrum. We will additionally study time-lensing methods for single-photons to further enhance the resolution of our time-domain characterizations.
