AbstractQuantum key distribution (QKD) can greatly benefit from photonic integration, which enables implementing low-loss, alignment-free, and scalable photonic circuitry. At the same time, superconducting nanowire single-photon detectors (SNSPD) are an ideal detector technology for QKD due to their high efficiency, low dark-count rate, and low jitter. We present a QKD receiver chip featuring the full photonic circuitry needed for different time-based protocols, including single-photon detectors. By utilizing waveguide-integrated SNSPDs we achieve low dead times together with low dark-count rates and demonstrate a QKD experiment at 2.6 GHz clock rate, yielding secret-key rates of 2.5 Mbit/s for low channel attenuations of 2.5 dB without detector saturation. Due to the broadband 3D polymer couplers the reciver chip can be operated at a wide wavelength range in the telecom band, thus paving the way for highly parallelized wavelength-division multiplexing implementations.

Significant Attention

Abstract Lithium niobate integrated photonics has recently received significant attention because it exploits the attractive properties of lithium niobate on an integrated platform which provides strong optical confinement as well as high photonic integration density. Although many optical functionalities of lithium niobate have been demonstrated on a chip in the telecom band, the visible and near-visible regimes are less explored. This is mainly because devices with a relatively smaller feature size are required which increases fabrication difficulty. Here, we explored the acousto-optic effect of lithium niobate on a chip at near-visible wavelengths (765–781 nm) and demonstrated acousto-optic modulation with the modulation frequency up to 2.44 GHz. We adopted an etchless process for the device fabrication and applied the principle of bound states in the continuum to optimize the device performance. By demonstrating functionality at near-visible wavelengths, our devices will enable many on-chip applications ranging from frequency metrology to quantum information processing.
