- Abstract
2.4 The first generation of THz integrated circuits on all-Si platform High-resistivity all-Si photonic crystal slabs have proven to be effective for integrating THz range components, including straight waveguides, waveguide bends, grating couplers [[89]] but also attenuators and resonators.
