A stellar interferometry has been recently proposed for the detection of gravitational waves in the frequency range of

. Intensity interferometry using two satellites would be a viable experimental approach for this space based stellar interferometer. When gravitational waves pass near separated two detectors constituting the intensity interferometry, photons that travel from the stellar source to each detector are experiencing the distortion of space-time, and this effect can change the number of detected photons in given detection time interval and also the value of the second-order correlation function
