  • Using a grating-based mode-splitting and reflector approach, a bidirectional chip-scale nanophotonic Kerr-resonator circuit that consumes 97% of the pump power to generate a soliton frequency comb at approaching unit efficiency with 65% conversion efficiency is reported.

  • The authors showcase a compact, energy-efficient multi-wavelength light source for scalable multi-Tb/s optical links. The system integrates a Kerr microcomb with a CMOS-compatible demultiplexer that requires zero tuning energy—advancing the design of practical, high-capacity WDM systems for data center and communication infrastructure.

  • Photonic-crystal ring resonators (PhCRs) offer direct control of nonlinear interactions. Here, authors explore the bandgap detuned excitation regime of PhCRs where they open bandgaps mode-detuned from the pump laser, and demonstrate OPOs and microcombs with low threshold power and high efficiency.

  • A Kerr-nonlinear resonator with normal dispersion supports bright and dark pulse states. With photonic crystal ring resonators, this work demonstrates a continuum across these nonlinear states and explores the underlying mechanism.
