Abstract
165We investigated the THz transmission characteristics of CW diode laser irradiation through a MM/polyimide/Si/MEH-PPV hybrid structure. The figure above shows the THz amplitude transmission spectra through the RB array with a bar length of 130 μm with varying laser irradiation. The corresponding absorption approaches 0.9 THz as the laser irradiation of I=0 W/cm2. With an increase in laser irradiation, the increased photo-excited charge carriers make the transmission weaker, resulting in an absorption increase. When the laser irradiation I=3 W/cm2, the THz transmission decreased to zero and a broadband spectra absorber was created.
