A photomixing technique for sub-THz wave generation using multimode laser diode (MLD) has been developed. To date, sub-THz spectra had a comb structure that was not suitable for application to spectroscopy. We succeeded in obtaining the improved spectral shape with broad background by optimizing the spot size of the MLD light on the photomixer in a cross-correlation spectroscopy in the sub-THz region.
