    Quantum cascade lasers (QCLs) are compact sources of coherent terahertz radiation. Although all existing QCLs use III-V compound semiconductors, silicon-based devices are highly desirable due to the high thermal conductivity and mature processing technology. We use a semiclassical rate-equation...

    In the present paper, we investigated the various elements of heat sources within a silicon carbide polymers (6H-SiC and 3C-SiC) semiconductor laser. The device employs 3C-SiC quantum well (QW) which is sandwiched between two layers of 6H-SiC as cladding regions that can be interpreted in terms...

    The authors have investigated laser action in ferroelectric liquid crystal (FLC) sandwiched between dielectric multilayers composed of SiO2 and TiO2. The single-mode laser action was observed at the band edge of FLC. The lasing threshold was much lower than that of simple FLC because of the...
