Paper Abstract

The combination of the optical and microwave techniques offers new approaches for the generation of microwave signals. That is made possible by the very high bandwidth of the optical devices and the very low attenuation of the optical fiber. The main general advantage of these approaches is the generation of very high frequencies with low noise. For the optical stabilization of microwave oscillators a clean reference signal is optically transmitted. However, instead of the millimeter wave signal, one of its subharmonics is optically transmitted and the millimeter wave signal is generated utilizing the subharmonic signal as a reference. This way the optical components become much simpler and cheaper. In this procedure a crucial point is the frequency division at millimeter waves. For this purpose a new method is introduced: the superharmonic injection locking of oscillators. Utilizing combined injection and phase locking techniques the frequency of the microwave oscillator is stabilized while its noise is significantly reduced.
