    Optical Defects as Sources of Quantum Light

    Article obtained from Photonics RSS Feed.

    Researchers at Stanford University are investigating light-emitting defects in materials that could someday enable quantum-based technologies. Once understood, these defects could be controlled and potentially provide bright, on-demand, predictable sources of quantum light.

    The researchers are specifically investigating hexagonal boron nitride (hBN), a material that can emit bright light one photon at a time at room temperature. Hexagonal boron nitride emits light in a rainbow of hues that currently cannot be controlled. “We wanted to know the source of the multicolor emission, with the ultimate goal of gaining control over emission,” researcher Fariah Hayee said.

    The scientists were able to trace the…
