Abstract

In the field of large scale radio interferometers, there is a growing need for the photonic highly-stable signal generation and distribution system. In order to maintain signal coherency of the distributed reference-frequency signal, we have developed a photonic millimeter-wave generator and a photonic transmission signal phase stabilizer to transmit a reference signal in the form of frequency difference between two coherent light waves.
