    Qiu, Yueming; Uhl, David; Keo, Sam (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2004, 2004-05-16)
    InAsSb quantum-dot lasers near 2 pm were demonstrated in cw operation at room temperature with a threshold current density of below 1 kA/cm, output power of 3 mW/facet and a differential quantum efficiency of 13%.
  • Development of efficient mid-IR interband cascade lasers for chemical sensing. 
    Yang, Rui Q.; Hill, Cory J.; Yang, Baohua; Qiu, Yueming; Jan, Darrell (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2006., 2006-02-08)
  • High-reliability pump module for non-planar ring oscillator laser 
    Liu, Duncan T.; Qiu, Yueming; Wilson, Daniel W.; Dubovitsky, Serge; Forouhar, Siamak (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2007., 2007-08-26)
    We propose and have demonstrated a prototype high-reliability pump module for pumping a Non-Planar Ring Oscillator (NPRO) laser suitable for space missions. The pump module consists of multiple fiber-coupled single-mode ...
  • Low power consumption lasers for next generation miniature optical spectrometers for major constituent and trace gas analysis 
    Forouhar, Siamak; Soibel, Alexander; Frez, Clifford; Qiu, Yueming; Chen, J.; Hosoda, T.; Kipshidze, G.; Shterengas, L.; Tsvid, G.; Belenky, G.; Franz, Kale J.; Gmachl, Claire; Scherer, Benjamin (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2010, 2010-07-11)
    The air quality of any manned spacecraft needs to be continuously monitored in order to safeguard the health of the crew. Air quality monitoring grows in importance as mission duration increases. Due to the small size, low ...
  • Mid-IR interband cascade lasers 
    Yang, Rui Q.; Hill, Cory J.; Qiu, Yueming (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2005., 2005-11-28)
    Efficient mid-IR interband cascade (IC) lasers are developed based on 111-V semiconductor materials to cover wavelength range from 2.7 to 5.6 μm. These IC lasers reuse injected electrons in cascade stages for photon ...
  • Reliability of semiconductor laser packaging in space applications 
    Gontijo, Ivair; Qiu, Yueming; Shapiro, Andrew A. (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2008, 2008-09-01)
    A typical set up used to perform lifetime tests of packaged, fiber pigtailed semiconductor lasers is described, as well as tests performed on a set of four pump lasers. It was found that two lasers failed after 3200, and ...
  • Self-assembled InAsSb quantum dots on (001) InP substrates 
    Qiu, Yueming; Uhl, David (American Institute of Physics, 2004-03-01)
    Self-assembled InAsSb quantum dots (QD) on (001) InP substrates have been grown using metalorganic vapor phase epitaxy. The dot density and size are found to be strongly dependent on the presence of arsine. Direct deposition ...
