摘　　要：This Letter demonstrates a filterless v-band signals and pulses generator scheme with a tunable optical carrier to sideband ratio（OCSR）. Through complete theoretical analysis, the mathematical expression of the OCSR that contains the extinction ratio, phase modulation index, and bias angle is obtained. It is found that the OCSR has a wide tuning range, from 50 to-70 d B. By careful adjustment, a 60 GHz millimeter-wave signal with the OCSR at 50.72 d B and the electrical spurious suppression ratio at 36.6 d B can be achieved. Moreover, the discussions of using optimum OCSR to generate a Nyquist pulse or triangular-shaped pulse are also presented in this Letter.This Letter demonstrates a filterless v-band signals and pulses generator scheme with a tunable optical carrier to sideband ratio（OCSR）.
