Purpose

The Small Teams project Quantum Photonic Integrated Circuits for Quantum Interconnects as a whole aims to develop a chip-based platform by which entangled photons can be generated and distributed between nodes in a quantum network. The emphasis of this particular collaboration, a sub-project of the Small Teams project will be on the development of technology that can deliver photons to external optical networks efficiently and at high rates in a robust package as required for practical implementation. Using nanowire quantum dot sources grown with a scalable site-controlled nucleation process and a transfer technique that allows for the incorporation of an arbitrary number of single emitters on-chip, the project team will develop a fully integrated on-chip platform for the production, manipulation and detection of quantum states of light. This collaborative project between Carleton and NRC will focus on, a fiber-tochip coupling device with primary design targets of high-efficiency, polarizationinsensitive and bandwidth-enhanced operation, as well as a reliable operation at 950 nm and 1550 nm.
