Fundamentals of Terahertz Wave Technology
What are Terahertz Waves?
The terahertz region of the electromagnetic spectrum lies between infrared and microwave frequencies, typically from 0.1 to 10 terahertz. Terahertz waves are known for their unique properties such as non-ionizing radiation and the ability to penetrate various materials like clothing, plastics, and ceramics.
Generation and Detection of Terahertz Waves
Fundamentals of generating terahertz waves involve utilizing either ultrafast lasers to create pulses of terahertz radiation or using electronic components like antennas or photoconductive switches. Detection methods include utilizing antennas, optical rectification, or cryogenically cooled bolometers to capture and analyze terahertz signals with high sensitivity and accuracy.
Another method for the generation of terahertz waves is through nonlinear optical processes like difference frequency generation. This method involves mixing two laser beams of different frequencies in a nonlinear crystal to produce terahertz radiation, providing an alternative approach for creating terahertz waves with specific characteristics.
