Researchers develop silicon chip-based quantum photonic devices


Ulsan National Institute Of Science


They used a hybrid approach combining silicon photonic waveguides with InAs/InP quantum dots that act as efficient sources of single photons at telecom wavelengths spanning the O-band and C-band. There are several potentially fruitful approaches to quantum information processing, including atom, light, and superconducting devices. Professor Kim focuses on the quantum information processing using light. Here, they used a hybrid approach that combines silicon photonic waveguides with InAs/InP quantum dots that act as efficient sources of single photons at telecom wavelengths spanning the O-band and C-band. The quantum optical device, developed by the research team has successfully transferred the emission from the quantum dots along the silicon photonic circuits with high efficiency.
