Deterministic integration on V-groove fiber arrays for multichannel quantum photonic platforms

Scalable, reliable single-photon sources are essential for quantum photonic technologies. In particular, a fiber-based platform is desirable form for practical single-photon devices. Although recent advances with solid-state quantum emitters on fiber platforms have enabled the generation of single photons with high-performance, the reliable, scalable implementation of multiple sources on the compact fiber platform remains challenging. Here, we present a multiple, tunable array of quantum photonic devices in the fiber-based platform. We developed the selective integration for multiple quantum dot devices, and implemented multi-channel single-photon device based on a V-groove fiber platform. The device offers scalability, tunability, high fabrication yield, and high single-photon coupling efficiency. Therefore, this fiber-integrated quantum platform provides a scalable and reliable multichannel single-photon source.
