摘要： Provided are a terahertz wave transmission and reception (Tx/Rx) module package and method of manufacturing the same. The complete and separate terahertz wave Tx/Rx module package is implemented by simply aligning a silicon ball lens, a photoconductive antenna and a focusing lens, and thus facilitates generation or measurement of a terahertz wave. The terahertz wave Tx/Rx module package and method can remarkably reduce time and cost required to build a terahertz wave generation and measurement system, and simplify and miniaturize the terahertz wave generation and measurement system. In addition, characteristics of a terahertz wave generated by the photoconductive antenna can be simply measured. Furthermore, the terahertz wave Tx/Rx module package can be stored and transported with a photoconductive antenna, a silicon ball lens and a focusing lens kept aligned as they are, and also it is possible to minimize pollution of terahertz wave devices caused by surroundings.
