Abstract
A novel coherent mid-infrared emission source, the transistor-injected quantum cascade laser, is designed and modeled. Band engineering of the quantum cascade laser ensures desired lasing wavelength and a plasmon-enhanced waveguide is employed to confine the optical field. By incorporating the quantum cascade lasing region into a conventional heterojunction bipolar transistor, independent control of current and field through the lasing region is achieved. Higher differential quantum efficiency and lower threshold current density are also predicted.
