Application of the strain engineering and new quinternary material into the \nactive region of light emitting diodes (LEDs) allowed for increasing the internal quantum efficiency more than \ntwofold. InAs/GaSb type II superlattice (SL) active region was used for the LWIR LEDs. It was experimentally \ndemonstrated that only a few periods in the SL contribute to the radiative recombination process, which concludes \nthat active region cascading with fewer periods will be more effective in the LWIR SL LED design. Application of the \ncascading scheme enabled type I QW \u039b=2 \u039cm LEDs generating record quasi-continuous wave (qCW) power of 10 \nmW at room temperature. Novel scalable pixel design and fabrication method realized highly dimensional LED arrays with \n512 x 512 pixels and the independently controlled dual color LED arrays emitting at 2 \u039c m and 3  \u039c m. A new \nprecise technique for calibration of LED power has been developed. For lasers, research has been focused on \ndevelopment of single mode tunable lasers. The diode lasers generating 100 mW room temperature CW power at 2 \u039cm \nwith diffraction limited beam shape have been fabricated using a cost effective wet etching technique. A new \nprinciple of laser tuning has been developed using optical pumping. Wavelength of quantum cascade lasers emitting at \n9 \u039c m was tuned as high as 3 nm at room temperature using optical control of the effective refractive index over \nthe lasing mode. A novel opto-pair scheme for methane detection was designed and demonstrated. The photodetectors \nwith nBn and nBp active region showed the specific detectivity of ~10<super>9</super> \ncmHz<super>1/2</super>/W at room temperature and were coupled with the LED emitting at 3.3 \u039cm."},{"label":"dcterms.available","value":"2013-05-22T17:34:51Z"},{"label":"dcterms.contributor","value":"Belenky, Gregory , Suchalkin, Sergey"},{"label":"dcterms.creator","value":"Jung, Seungyong"},{"label":"dcterms.dateAccepted","value":"2015-04-24T14:46:48Z"},{"label":"dcterms.dateSubmitted","value":"2015-04-24T14:46:48Z"},{"label":"dcterms.description","value":"Department of Electrical Engineering"},{"label":"dcterms.extent","value":"153 pg."},{"label":"dcterms.format","value":"Application/PDF"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/1951/59711"},{"label":"dcterms.issued","value":"2012-12-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Made available in DSpace on 2013-05-22T17:34:51Z (GMT).
