Paul Horowitz works on experimental electrical circuits and astronomical instrumentation, including radio and optical searches for extraterrestrial signals. His institutional account describes designs that combine optical collection with fast photodetectors.[ref]
Paul Horowitz by Harvard Department of Physics. Authored research description: experimental electronics and optical/radio searches
Such searches turn a candidate pulse into a measurement problem involving timing, noise, detector response and independent checks. Instrument sensitivity and interference rejection determine which signals a null result can exclude; absence of a detection alone does not specify every possible source model.
