Advances In Optical And Microwave Technology To Direct Detection In The Far Infrared And Submillimeter Heterodyne Receivers

A summary of recent advances in device and component technology in the far infrared range and in the submillimeter range of the spectrum will be presented. Technology for the Eos experiment, Spectroscopy of the Atmosphere using Far Infrared Emission (SAFIRE) will be presented, as representative of new direct detection technology in the 20 to 150 micron range of the electro-magnetic spectrum. In the past 5 years new optical and microwave technologies have become available and can be combined to provide the devices needed to build heterodyne receivers for radiation at frequencies between 600 GHz and 5 THz. We present a summary of presently available submillimeter detection systems and the previous limitations on heterodyne detectors. Two techniques are discussed which may prove to enable heterodyne receivers to bridge the gap between optical and millimeter wavelengths, We conclude that new technology in the optical and microwave domain show promise for enabling heterodyne receivers with greatly improved spectral range..
