  1. 1. Simulation of THz Quantum Cascade Lasers

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Viktor Rindert; [2021]
    Keywords : Physics and Astronomy;

    Abstract : Quantum Cascade Lasers (QCLs) have since their invention in 1994 become a crucial source for mid-infrared and THz radiation. Mid-infrared QCLs have achieved room temperature operation while THz QCLs have not. As such, simulations are an important tool in order to achieve a THz QCL operational at room temperature.

  4. 3. Interface Roughness in Quantum Cascade Lasers

    University essay from Lunds universitet/Matematisk fysik

    Author : Kasparas Antanas Krivas; [2015]
    Keywords : Quantum Cascade Lasers; Interface Roughness; Modeling; Physics and Astronomy;

    Abstract : The quantum cascade laser (QCL) is a solid state device capable of generating the coherent mid-infrared and terahertz radiation. It is made from layers of different semiconducting materials. This layered structure gives rise to sub-bands, that are employed to achieve charge inversion necessary for lasing. READ MORE

  5. 4. Generation of Short Intense Terahertz pulses Through Optical Rectification

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Author : Carl Ekström; [2015]
    Keywords : Terahertz; THz; Optical Rectification; OR; Photonics; Optics; LiNbO3; Physics and Astronomy; Technology and Engineering;

    Abstract : The lack of sources that generates intense THz pulses have in many years limited the field of THz science. Until recently intense THz pulses have been hard to generate using nonlinear crystals such as Lithium Niobate (LiNbO3) with high efficiency. READ MORE
