THz Generation Process in LT-GaAs
Optical down-conversion is the most successful commercial technique for THz generation using Low temperature grown GaAs (LT-GaAs). The technique is often known as Terahertz Time-Domain Spectroscopy (THz-TDS). This technique works by optical pulse excitation of a photoconductive switch. Here, a [...]
PAM-XIAMEN can offer 2” InGaAs/InP epi wafer for PIN as follows. InGaAs is the compound of InAs and GaAs. In the periodic table of chemical elements, In and Ga are elements of the third group, and As is the fifth group element. The properties of InGaAs [...]
