Abstract

We have proposed high resolution spectroscopy based on an optical frequency comb and heterodyne detection method, whose measurement frequency range has already achieved to be 3 THz (1530 nm~1560 nm) with a spectral resolution of less than 1 MHz. Also, the absolute frequency axis is guaranteed less than 1 MHz. In this presentation, we will show the experimental results including dynamic range of the proposed system.
