Terahertz emission and detection using Ge-on-Si photoconductive antennas
Dhanashree Chemate, Abhishek Singh, Utkarsh Pandey +5
Germanium-on-Silicon (Ge-on-Si) is a promising, CMOS-compatible platform for integrated terahertz (THz) photonics, offering a low-cost alternative to III-V semiconductors. A primar…

Exploring angle-dependent Phonon Modes in Sodium Mesitylene Sulfonate (SMS) crystals using THz-time domain polarimetry (THz-TDP)
Yamuna Murtunge, Ajinkya Punjal, Ruturaj Puranik +3
We employed sodium mesitylene sulfonate crystals to investigate angle-dependent phonon resonance and thickness-dependent splitting in THz time-domain polarimetry. This crystal poss…
