Perovskite Waveguides Offer Quantum, Integrated Device Capabilities
A research team from the University of Warsaw, in collaboration with institutions in Europe and Australia, developed a way to efficiently fabricate large-scale waveguiding perovskite crystals in predefined shapes such as couplers, splitters, or microwires. The optical, lasing, and waveguiding capabilities of perovskite make the material a promising platform for integrated photonic circuits for classical and quantum signal processing.

Integrated Photonics Shrinks Down GPS-Free Navigation Tech
Researchers from Sandia National Laboratories have used silicon photonic microchip components to perform a quantum sensing technique called atom interferometry, an ultra-precise way of measuring acceleration. It’s the latest milestone toward developing a kind of quantum compass for navigation when GPS signals are unavailable.
