Abstract :
The design and fabrication of resonators and waveguides, operating at THz frequencies are reported. Resonance frequencies, mode confinement, quality factors, and stop-bands were calculated for resonators with and without photonic elements. The estimations show that very narrow modes can exist within the propagation bandgap of a photonic lattice. Microdisk devices were designed and fabricated for high-quality whispering-gallery modes centered around 10 THz. Combined with silicon-germanium quantum wells grown by molecular beam epitaxy, these resonators are promising candidates for silicon-based miniature far-infrared lasers.
