TERAHERTZ
TECHNOLOGIES: RADIATION DETECTORS FOR THE FAR INFRA RED
Technologies in the Terahertz
frequency range (1-10 THz, or 300-30 µm wavelengths) have lagged technologies
in the nearby microwave and infrared frequency ranges. Among the many devices
now being developed and improved are radiation detectors. Current ones operate
by means of thermal excitation and require cooling to temperatures below 4K
- a task which can be very time consuming. At present, the Sherwin Group possesses
a protype THz detector that does not require any cooling. Our task
thus far has been to learn more about the detector and get it fully operational.
Over the last few weeks, we have focused primarily on building antennas for
this detector. More specifically, we have been using an etchant consisting
of potassium ferro-cyanide, sodium cyanide, and de-ionized water to chemically
sharpen the gold wires that will serve as the antennas for this detector.
