Terahertz Link with Orthogonal Polarization over Silicon Dielectric Waveguide

The authors studied the transmission performance for orthogonal polarization fundamental modes in a dielectric silicon terahertz waveguide for doubling the data rate. The maximum data rate of practical error-free condition (bit-error rate < 10(-11)) for both polarizations is comparable over 20 Gbit/s under on-off keying modulation at 0.3-THz band.
