1. Realization of extremely broadband quantum-dot superluminescent light-emitting diodes by rapid thermal-annealing process

   Explore Article Optics Letters (Jun 24 2008)

   he first demonstration, to our knowledge, of the creation of ultrabroadband superluminescent light-emitting diodes using multiple quantum-dot layer structure by rapid thermal-annealing process is reported. The device exhibits a 3 dB emission bandwidth of 146 nm centered at 984 nm with cw output power as high as 15 mW at room temperature corresponding to an extremely small coherence length of 6.6 μm (Read Full Article)

   Haohua Tu, Daniel L. Marks, Yee Lin Koh, and Stephen A. Boppart Continuum generation from normally dispersive ultrahigh-numerical-aperture fibers deteriorates in relatively short times, limiting its application as a practical optical source for high-resolution optical coherence tomography. We find that reversible light-induced structural modification of fiber optic materials, rather than permanent optical damage, is responsible for this deterioration. By examining how the optical properties of corresponding light-induced waveguides depend on ... (Read Full Article)
