Microwave harmonic frequency generation utilizing the properties of an optical phase Modulator

New techniques to generate a harmonic microwave frequency modulated on an optical carrier are presented. All these techniques utilize the polarization-dependent properties of a LiNbO/sub 3/-phase modulator and manage to achieve 40-GHz modulation using only 10-GHz electronics. The signal quality of t...

Zusammenfassung:	New techniques to generate a harmonic microwave frequency modulated on an optical carrier are presented. All these techniques utilize the polarization-dependent properties of a LiNbO/sub 3/-phase modulator and manage to achieve 40-GHz modulation using only 10-GHz electronics. The signal quality of the generated frequency is mainly determined by the 10-GHz signal generator, and the suppression of undesired lower order harmonic frequencies exceeds 30 dB.
