The nuclear spins of low-density implanted Ga atoms in Ge are interesting candidates for solid state-based qubits. To date, activation studies of implanted Ga in Ge have focused on high densities. Here we extend activation studies into the low-densit

Novel transverse-mode behavior and bistability are observed in spectral and far-field measurements of terahertz-distributed feedback quantum cascade lasers. Prior to onset of negative differential resistance (NDR) at the maximum superlattice current,

Terahertz quantum cascade lasers (QCLs) have been used together with a monolithic planar Schottky diode receiver to study the heterodyne mixing between dual internal modes of a QCL and between a single mode of a QCL and a known molecular line from a
