Abstract

The optical frequency comb is a special light source that has spectral components of equal frequency intervals and is useful for various photonic measurements. In this paper, we propose a method to reduce the design and control difficulty of an etalon spectrometer, which is effective for optical frequency comb measurement. In the method, spectral data of the target optical frequency comb are obtained from a low-resolution etalon spectrometer by performing deconvolution data processing using the original algorithm called the inverse matrix data processing. This method makes it possible to measure the optical frequency comb more easily and cost-effectively.
