Novel optical fiber dispersion monitor using optical single sideband modulation

Summary form only given. We propose a novel method of GVD measurement using optical single sideband (SSB) modulation. In the proposed method, we alternate the sideband of the probe light between upper and lower frequency sides, and determine the GVD value from the phase shift induced by the alternation of the sideband. The accuracy and dynamic range of this method is high, and the sign as well as the absolute value of the GVD can be measured only from the output light without any extra procedures.
