Abstract:
To provide a method and device capable of easily measuring the CMRR vs. frequency characteristics of an optical receiver. Light having a measurement frequency (ω [hz]) is split into two different paths, and a first optical two-tone signal, which is signal light and has a frequency difference (ω−Δω [hz]), and a second optical two-tone signal, which is local light and has a frequency difference (ω-Δω [hz]), are obtained and input into a coherent receiver to be measured, wherein electrical signals output from the receiver are measured to obtain both the ratio of the intensity of a signal component having the frequency ω−Δω [hz] to the intensity of a signal component having the frequency ω [hz], which corresponds to the CMRR on the signal light side, and the ratio of the intensity of a signal component having the frequency ω+Δω [hz] to the intensity of the signal component having the frequency ω [hz], which corresponds to the CMRR on the local light side.

Claim (Index 2):
A common mode rejection ratio measurement device for a coherent optical receiver according to  claim 1 ,\n wherein the electrical signal measurement device ( 13 ) further comprises a function of obtaining the common mode rejection ratio (CMRR) on the locally generated light side from the intensity ratio of the intensity I \u03c9  of the electrical signal corresponding to the frequency \u03c9 [Hz] outputted as the differential component of the first optical two-tone signal which is the signal light and the second optical two-tone signal which is locally generated light, and the intensity I \u03c9\u2212\u0394\u03c9  of an electrical signal corresponding to the frequency difference (\u03c9+\u0394\u03c9 [Hz]) of only the second optical two-tone signal which is the locally generated light.
