Abstract
In this paper, millimeter-wave signals are generated with characteristics of high gain and low noise using optical frequency comb, where generated signals are tunable at a wider range (approx 50 GHz in both the sides) around the central frequency 94 GHz. Concept of electrical mixing is incorporated to achieve the tuning of the signals. Result shows that adopted methodology is far superior to conventional optical mixing and stable, high gain and low noise microwave signals are obtained in all the tuned frequencies. Wider tuning range speaks about the supremacy of the proposed scheme both in optical as well as in RF spectrum.
