Doping layers like the emitter or a surface field in silicon solar cells have to fulfill two important functions: They have to allow ohmic contact formation and they should also suppress Auger and surface recombination effects. The latter can be supp

Terahertz pulse generation is demonstrated by a resonant femtosecond interband excitation of the miniband of a quantum cascade laser. The laser gain is subsequently used to amplify the generated terahertz pulse as it propagates through the cavity.

Integrated THz pulse generation and amplification in THz QCLs is demonstrated. Intracavity narrowband THz pulses are generated at 2.1THz by exciting the facet of a THz quantum cascade laser with a resonant interband-intersubband transition and detect

Integrated terahertz (THz) pulse generation and amplification in a THz quantum cascade laser (QCL) is demonstrated. Intra-cavity THz pulses are generated by exciting the facet of the quantum cascade laser with an ultrafast Ti:Sapphire laser (~100fs)
