The integration of photonic crystal (PC) resonators into the active region of terahertz quantum cascade lasers emitting around 2.7 THz is presented. The PC acts as frequency selective mirror and allows the tuning of the emission frequency throughout the entire gain region of the active zone. The PC and the gain region are embedded in a double-metal wave guide.

We present a new physical model for describing heterogeneous dielectric mixtures in the terahertz frequency range, which overcomes drawbacks of established models. The theory is confirmed by highly accurate data on polymeric compounds.

Weak counter-propagating pulse trains or multiple quasi-cw waves can induce complex amplitude and phase modulated structures in the high-harmonic field. These ldquophotonicrdquo structures can be used for quasi-phase-matching the high-harmonic generation process.

An optical scattering theory is introduced that predicts significant disorder-induced resonance shifts in photonic-crystal nanocavities. Even for nm-scale imperfections, we calculate blue shifts of several meV, two orders of magnitude larger than the cavity linewidth.

We demonstrate Fourier transform coherent anti-stokes Raman scattering (FTCARS) microscopy and show that an external field combined with the signal can overcome detector dark noise. We discuss conditions for obtaining shot-noise-limited detection and compare the S/N of FTCARS with other methods.
