    Integrating 2D Materials for On-Chip Photonics

    Recently, the introduction of nonlinear optical functions in integrated optics has sparked significant enthusiasm. Demonstrations have shown the potential for integrated photonic platforms. Furthermore, large-scale manufacturing...
  • The two rings in the image are microresonators The bigger ring is the one where the microcomb is generated The microcomb is formed by a pulse of lighthere illustrated with a red spike and also known as a soliton - that recirculates in the cavity forever T

    Microcombs Made Ten times More Efficient

    Microcombs can help us discover planets outside our solar system and track new diseases in our bodies. But current microcombs are inefficient and unable to reach their full potential. Now, researchers at Chalmers University of...
