  • Practical implementations of quantum photonic circuits consist primarily of large waveguide networks to path-encode information. Here, Mohantyet al. demonstrate quantum interference between transverse spatial modes in a single silicon nitride waveguide, enabling robust quantum information processing.

  • Optical frequency combs in the mid-infrared are required for molecular gas detection applications but their realization in compact microresonator-based platforms is challenging. Here, Griffith et al. demonstrate on-chip broadband comb generation on a silicon microresonator spanning from 2.1 to 3.5 μm.

  • The Authors present an exciting dielectric waveguide mechanism that can confine light in regions of varying sizes, unlike conventional designs. The platform offers a unique blend of properties by leveraging radiation modes while minimizing optical losses. This work holds promise for serving as the next generation of fundamental building blocks for integrated photonics applications.

  • Nonlinear optical interactions can be substantially enhanced by the wavelength-scale confinement in integrated photonics, providing transformative capabilities for controlling, enhancing and manipulating material nonlinearities in miniaturized platforms. In this Review, we outline the design principles that harness the potential of nonlinear optical materials on integrated platforms and their utility in applications including broadband frequency conversion, frequency-comb generation, quantum light sources and nonlinear optical quantum logic gates.

  • A chip-scale laser platform based on silicon nitride ring resonators and commercial Fabry–Pérot laser diodes is developed for the wavelength range from 404 nm to 785 nm. The achieved coarse and fine tunings are up to 12.5 nm and 33.9 GHz, respectively, with kilohertz-scale linewidths and side-mode suppression ratios above 35 dB.
