Article Synopsis
- The study explores how terahertz waves can be converted to lower frequencies when passing through a GaAs waveguide, specifically at the temporal boundaries created by photoexcitation.
- The photoexcited waveguide facilitates the coupling of different electromagnetic modes, leading to a phenomenon known as frequency down-conversion, with efficient results confirmed by experimental data.
- The findings indicate that the direction of frequency conversion can be controlled by altering the polarization of the incoming waves, which could enhance terahertz communication systems by enabling efficient signal interconversion across various frequency channels.
