Abstract
We demonstrate a precise in-situ loss measurement technique using in-line silicon photodetectors. By measuring the photocurrents from silicon photodetectors embedded in a silicon waveguide, we extracted the waveguide loss with a standard deviation of 0.03 dB/cm based on 100 repeated measurements.
