Abstract

The use of narrowband tunable THz radiation for biomedical sensing applications is discussed. The THz radiation is generated via optical rectification in periodically poled nonlinear materials in a frequency range from 100 GHz to 3 THz. Center frequency and bandwidth can easily be adjusted to the requirements of the application. Different THz sensors utilizing evanescent THz fields are presented including waveguides and photonic bandgap structures.
