This research presents the calculation method of transmittance, reflectance and loss for hybrid output coupler (HOC). We introduce Q factor for loss analyses to evaluate the quality of HOC. We simulate the suppression of F-P etalon effect and distortion of output THz beam pattern with a wedged substrate. A 0.3 wedge angle makes transmittance not sensitive to small change of wavelength and substrate thickness. The distortion introduced by the 0.3 wedge angle will not dramatically change the Gaussian beam pattern.
