The balanced photodetector (BPD) is an important component for high-speed coherent receiver. An optimization strategy of waveguide-based multi-quantum well (MQW) BPDs, operating at 1550 nm is ...

Near-infrared Single Photon Avalanche Diodes (SPADs) are the dominant, practical single photon detectors for quantum applications and low-level optical sensing. Although some infrared SPADs can ...

Photonic qubits can represent an ideal choice in quantum information science since photons travel at the speed of light and interact weakly with the environment over long distances. In this context, ...

Colloidal perovskite quantum dots (PQDs) have emerged as highly promising single photon emitters for quantum information applications. Presently, most strategies have focused on leveraging quantum ...
