  • Microdisk lasers are useful for compact wavelength-scale photonic devices and circuits, but their operation by electrical injection can hamper their optical properties. Kimet al. show that a graphene-contact electrode provides efficient electrical injection while minimising optical losses.

  • Though laser action has been reported for optical bound states in the continuum (BIC) cavities with high quality factors, these BIC lasers lacked practical applicability. Here, the authors report an ultralow-threshold super-BIC laser featuring merged symmetry-protected and accidental BICs.

  • Flexible, millimetre-scale systems and devices require embedded, reliable micrometre-scale components, which can be challenging to achieve for optical sensors. Here, the authors design a photonic crystal nanolaser and demonstrate its use in measuring strain.
