Photonische Lokaloszillatoren für Anwendungen in der Terahertz-Radioastronomie

Kategorien: Radioastronomie

Zusammenfassung

Photonic Local Oscillators (PLOs) operating at optical wavelengths around 1550 nm have a major importance especially for radio astronomic THz Antenna arrays like the "Atacama Large Millimeter/Submillimeter Array" (ALMA) in Chile. The PLO-Technique allows the distribution of a centrally generated Local Oscillator signal over more than ten kilometres to the Antennas, by using the optical Window for long distance communications where loss in glass fibres is lowest...
