The emission frequency of mesas was determined using a Michelson interferometer setup which also demonstrates polarized emission. Interference patterns of THz radiation from Bi2212 mesas were detected by various detectors such as a liquid helium cooled silicon composite bolometer, a Golay cell and a pyroelectric detector. An emitted power as high as 0.06mW was detected from Bi2212 mesas. For the first time, most of the pumped power was extracted as THz emission from a Bi2212 mesa. The radiation at 0.54THz was detected using the Michelson interferometric setup.eninfo:eu-repo/semantics/openAccessMichelson interferometersTerahertz (THz) wavesSilicon detectorsMesa structuree-Beam lithographyArticle2-s2.0-8486853571410.1088/0953-2048/25/12/125004
