We use first principle DFT-based microscopic many-body models to investigate essential electro-optical properties of bulk tellurium. Absorption/gain and spontaneous emission spectra are calculated using the semiconductor Bloch and luminescence equations. High harmonic generation due to off-resonant excitation and its propagation dependence are studied by coupling the microscopic models to a pulse propagator. Limitations due to intrinsic carrier losses via radiative- and Auger-recombination processes are determined solving quantum-Boltzmann type scattering equations. The strong directional- as well as density- and temperature-dependence of the properties is demonstrated. © 2023 SPIE.Note
