There has been great progress recently in the intensity of broadband Terahertz (THz) signals utilizing surface and field effects from semiconductor materials. Typically, the Photo-Dember effect combined with optical rectification in such materials as GaAs or InAs generates the most intense broadband THz radiation from contactless THz emitters [1]. There still exists room for improvement in terms of...
By utilizing the spontaneous and piezoelectric polarization inherent in wurtzite III-V nitride semiconductors, the insertion of a strained layer of InGaN, AlN or InN along the [0001] crystal orientation of GaN will result in large sheets of fixed charges. The permanent dipole resulting from these charges contribute directly to the high electric field in these layers that bends the conduction band...
Using varied stripe length method we systematically studied optical gain properties of blue‐green 3 nm InGaN QWs grown on c‐plane and (11−22) semipolar substrates. We determined that for such structures when the product of modal net gain at peak and stripe length exceeds factor 5 the gain saturation occurs due to depletion of pumped carriers. We then focused our attention on the gain in unsaturated...
