Broadband High-Resolution Fourier Spectrometry with Chip-Scale Combs

Electrically-pumped optical frequency combs have emerged as promising candidates for broadband, high-resolution optical sensing. Here we show how their unique emission properties can be leveraged in Fourier spectrometers with millimeter-long optical delays to obtain resolution enhancements by orders...

Summary:Electrically-pumped optical frequency combs have emerged as promising candidates for broadband, high-resolution optical sensing. Here we show how their unique emission properties can be leveraged in Fourier spectrometers with millimeter-long optical delays to obtain resolution enhancements by orders of magnitude without any optical setup modifications.
