  • Frequency-stable laser systems are important for many applications, like optical communications, that require high precision and low noise. Here, Idjadi and Aflatouni demonstrate that the widely used Pound-Drever-Hall technique can be fully integrated on-chip, miniaturizing the stabilization setup.

  • Implementing stable lasers often requires complex packaging of multiple devices, such as stand-alone external cavities and isolators. Now, stabilizing and isolating lasers can be realized in a single silicon chip thanks to the Kerr nonlinear effect in a resonator.

  • Magnetostatic wave filters have a wide working frequency range, small size and high Q-factor, however, they are hampered by the need for a large external electromagnet to provide a bias magnetic field. Here, Du et al demonstrate an extremely small and low power external magnetic bias assembly with zero static power consumption, removing the need for bulky and energy intensive electromagnets.
