Outline of Final Research Achievements

In this project, we developed a high speed, high precision polarization-sensitive dual comb spectroscopy system in the near infrared spectral region. We proposed the original idea of the system as a combination of dual-comb spectroscopy and rotating compensator polarimetry to generate new com lines with polarization information as the frequency sidebands of each comb tooth. We constructed the system and succeeded in determining the polarization information for each optical frequency component constituting the optical frequency comb light source. We also proposed a measurement method and an analysis method to reduce measurement uncertainty. Furthermore, we constructed the original system for future application of the proposed polarization-sensitive dual comb spectroscopy.
