A collinear 2f-to-3f self-referencing interferometer with a dual-pitch PPLN ridge waveguide

摘要

We report carrier-envelope offset beat detection (52-dB signal-to-noise ratio at 100-kHz resolution bandwidth) with a common-path 2f-to-3f self-referencing interferometer with a dual-pitch periodically poled lithium niobate ridge waveguide.
