When photons can be used to transmit information at the speed of light, quantum light sources, connected with quantum fiber optic cables and detectors, will be a requirement. An international team led by physicists at the Technical University of Munich (TUM) has taken a step toward providing light sources for quantum technologies, by creating quantum light sources in atomically thin material layers and positioning them within the material with nanometer-scale accuracy. The ability to precisely control the placement of the light sources is critical to their value, the researchers said....Read full articleRelated content from Photonics MediaARTICLESMaterials Integrated with Silicon Photonics Manipulate Light Phase at Low LossA Columbia University team used a 2D material from the transition metal dichalcogenide (TMD) class to control the phase of light without changing its amplitude or depleting its power.
