Up-Scale: Frequency Converter Enables Ultra-High Sensitivity Infrared Spectrometry

Caption

A lithium niobate waveguide (bottom left) combines a pump laser and a near-infrared signal, "up-converting" the signal to a visible wavelength. Two prisms (right) separate the signal from the combined beam and send it to an avalanche photodiode detector (top left), which reads the up-converted signal.
