  text: Injecting spin-polarized carriers into semiconductor lasers provides important
    opportunities to extend what is known about spintronic devices, as well as to
    overcome many limitations of conventional (spin-unpolarized) lasers. By developing
    a microscopic model of spin-dependent optical gain derived from an accurate electronic
    structure in a quantum-well-based laser, we study how its operation properties
    can be modified by spin-polarized carriers, carrier density, and resonant cavity
    design. We reveal that by applying a uniaxial strain, it is possible to attain
    a large birefringence. While such birefringence is viewed as detrimental in conventional
    lasers, it could enable fast polarization oscillations of the emitted light in
    spin lasers, which can be exploited for optical communication and high-performance
    interconnects. The resulting oscillation frequency (>200 GHz) would significantly
    exceed the frequency range possible in conventional lasers.

  text: Injecting spin-polarized carriers into semiconductor lasers provides important
    opportunities to extend what is known about spintronic devices, as well as to
    overcome many limitations of conventional (spin-unpolarized) lasers. By developing
    a microscopic model of spin-dependent optical gain derived from an accurate electronic
    structure in a quantum-well-based laser, we study how its operation properties
    can be modified by spin-polarized carriers, carrier density, and resonant cavity
    design. We reveal that by applying a uniaxial strain, it is possible to attain
    a large birefringence. While such birefringence is viewed as detrimental in conventional
    lasers, it could enable fast polarization oscillations of the emitted light in
    spin lasers, which can be exploited for optical communication and high-performance
    interconnects. The resulting oscillation frequency (>200 GHz) would significantly
    exceed the frequency range possible in conventional lasers.
