    • This provides a semiconductor laser device of a high light output efficiency, which is high in current confinement effect, small in leak current, and favorable in temperature property, and indicates a low threshold current, and can effectively confine laser light to a stripe region, and is favorable in beam profile. This semiconductor laser device (100) includes the laminated structure of an n-AlInP clad layer (103) a superlattice active layer section (104), a p-AlInP first clad layer (105), a GaInP etching stop layer (106) are formed, and on top of that, there are a p-AlInP second clad layer (107), a GaInP protective layer (108) and a p-GaAs contact layer (109), which are processed into a stripe-shaped ridge. A p-side electrode (111) is directly coated and formed on the etching stop layer of ridge top surface, ridge sides and ridge flanks since s the superlattice active layer section is sandwiched between the n-AlInP clad layer and the p-AlInP first clad layer, an energy band gap difference from the active layer section becomes greater.

    • The first phonon-pumped semiconductor laser. The active region is an unbiased boron-doped Si0.94Ge0.06/Si superlattice with Si0.97Ge0.03 buffer layers embedded in a surface-plasmon strip waveguide. Warm and cool heat sinks create a temperature gradient across the waveguide. A heat buffer layer adjacent to the cool sink reflects optical phonons and transmits acoustic phonons. Within the resonator, the difference in effective temperatures of optical and acoustic phonons provides hole pumping for the lasing transition between the heavy-hole 2 (HH2) and heavy-hole 1(HH1) minibands. A gain of 280/cm at the 5THz emission frequency is predicted for 6×1017/cm3 doping at temperatures of 300K and 77K for optical and acoustic phonons, respectively.
