In observations with ALMA (Atacama Large Millimeter / submillimeter Array), a gigantic radio telescope which will be constructed at 5000 - meter altitude in Chile, this generation technique of millimeter / submillimeter wavelengths using the photonic technology will play an important role in detecting faint radio signals from the universe.

Astronomers using the National Science Foundation's newly commissioned Green Bank Telescope have detected remarkably faint radio signals from an 820 year - old pulsar, making it the youngest radio - emitting pulsar known. (public.nrao.edu)
They found these molecules not with optical telescopes but by tuning in with exquisitely sensitive antenna dishes that can receive the extremely faint radio signals generated by molecular clouds. (sciencemag.org)
