Cambridge, MA – In a significant advancement in the field of photonics, researchers at Harvard University have engineered a chip-scale device that can dynamically manipulate the ‘handedness’ of light, a characteristic referred to as optical chirality. This innovative development, detailed in the journal Optica, holds promise for a variety of applications including chiral sensing, optical communication, and quantum photonics.
The device is based on a twisted bilayer photonic crystal, which enables the control of light’s chirality with unprecedented precision. Optical chirality is a crucial property that influences how light interacts with matter, and this new technology may enhance our understanding and usage of light in complex systems.
As researchers continue to explore the implications of this breakthrough, it opens new avenues for advancements in multiple disciplines. The ability to manipulate light’s handedness could lead to more efficient optical communication systems and improved sensing technologies that rely on chiral molecules.
