Efficient Ultra-Broadband Microcombs in Photonic Molecules
Paper in proceeding, 2026
We demonstrate 100GHz repetition rate microcombs in silicon nitride, achieving 18% optical conversion efficiency and 600nm spectral width. This results in a compact and efficient platform for chip-scale optical frequency division and microwave generation.
