Abstract
In the present study, we fabricated novel electro-optic (EO) phase modulators using EO polymer waveguides and gold antenna arrays for continuous-wave terahertz (THz) detection. We used a cyclo-olefin polymer (COP) with very small absorption losses and low dielectric constants in the THz region as a substrate, enabling relatively large antenna size with small absorption loss for increasing modulation efficiency. By irradiating W-band (75-110 GHz) electromagnetic waves on the devices, we observed modulation sidebands in the measured optical spectra and successfully demonstrated the electromagnetic wave detection.
