Theoretical studies of subband carrier lifetimes in an optically pumped 3-level terahertz laser
Non-radiative (phonon scattering) lifetimes are calculated for asymmetric quantum well structures in the AlGaAs/GaAs materials system. Structures are designed in a 3-level optically pumped laser configuration, and tuned for emission in the terahertz frequency range. For emission frequencies below 8.7THz, the energy gap of the lasing levels is less than the LO phonon energy in GaAs, which leads ...
متن کاملTerahertz surface plasmons in optically pumped graphene structures.
We analyze the surface plasmons (SPs) propagating along optically pumped single-graphene layer (SGL) and multiple-graphene layer (MGL) structures. It is shown that at sufficiently strong optical pumping when the real part of the dynamic conductivity of SGL and MGL structures becomes negative in the terahertz (THz) range of frequencies due to the interband population inversion, the damping of th...
متن کاملFrequency stabilization of a single mode terahertz quantum cascade laser to the kilohertz level.
A simple analog locking circuit was shown to stabilize the beat signal between a 2.408 THz quantum cascade laser and a CH(2)DOH THz CO(2) optically pumped molecular laser to 3-4 kHz (FWHM). This is approximately a tenth of the observed long-term (t approximately sec) linewidth of the optically pumped laser showing that the feedback loop corrects for much of the mechanical and acoustic-induced f...
متن کاملLASERS WITHOUT INVERSION: DENSITY OPERATOR METHOD
A quantum theory of a two and three-level laser with injected atomic coherence is developed by using a density operator method, to the best of our knowledge, for the first time. The initial atomic coherence plays an essential role. At steady state, the equation of motion for the density operator yields to exhibit laser without inversion and a phase locking but no threshold for the laser fie...
متن کاملVertical cavity surface emitting terahertz laser.
Vertical cavity surface emitting terahertz lasers can be realized in conventional semiconductor microcavities with embedded quantum wells in the strong coupling regime. The cavity is to be pumped optically at half the frequency of the 2p exciton state. Once a threshold population of 2p excitons is achieved, a stimulated terahertz transition populates the lower exciton-polariton branch, and the ...
