摘要：

We present flattened supercontinuum generation from a micro-resonator-based frequency comb for the calibration of astronomical spectrographs. Micro-resonator-based frequency combs, also known as microcombs, exhibit inherently high mode spacing owing to their compact cavity size. Applying a tailored photonic crystal fiber (PCF) taper, the spectrum of a 12 GHz microcomb is broadened to more than one octave from 1.0 mu m to 2.2 mu m. The resulting supercontinuum is smoothed using a spatial light modulator based spectral flattener, producing a flat-top broadband supercontinuum that serves as a powerful source for precision astronomical spectroscopy.
