  • By controlling the group velocity dispersion of a microresonator through proper shape design, scientists generate a comb whose central frequency can be tuned throughout the transparency window of the microresonator host material.

  • Optoelectronic and photonic devices require materials with multiple, often conflicting functionalities, leading to integration challenges. Here, the authors demonstrate that layered PdSe2 is suitable for infrared photodetection, light guiding and photothermal applications due to its peculiar semimetallic band structure.

  • Principal optical axes define light-matter interactions in crystals and they are usually assumed to be stationary. Here, the authors report the observation of wavelength-dependent principal optical axes in ternary van der Waals crystals (ReS2 and ReSe2), leading to wavelength-switchable propagation directions of their waveguide modes.

  • A soliton microcomb as an astronomical spectrograph calibrator is presented. It can ultimately have a footprint of a few cubic centimetres, and reduced weight and power consumption, attractive for precision radial velocity measurement.
