Towards fibre-like loss for photonic integration from violet to near-infrared.

ABSTRACT: Over the past decades, remarkable progress has been made in reducing the loss of photonic integrated circuits (PICs) within the telecom band^1-4, facilitating on-chip applications spanning low-noise optical⁵ and microwave synthesis⁶, to lidar⁷ and photonic artificial intelligence engines⁸. However, several obstacles arise from the marked increase in material absorption and scattering losses at shorter wavelengths^9,10, which prominently elevate power requirements and limit performance in the visible and near-visible spectrum. Here we present an ultralow-loss PIC platform based on germano-silicate-the material underlying the extraordinary performance of optical fibre-but realized by a fully CMOS-foundry-compatible process.
