Frequency domain optical coherence tomography (FD-OCT) allows interferometer topologies with simplified system construction and handling. Problems of dispersion and polarization matching between the sample and reference arms, as well as beamsplitter spectr ...
Herein, a study of combining refractive microlenses arrays and nanostructured antireflective surfaces is presented. Fabrication method is surveyed for obtaining the hybrid surface with functionalities of refractive and antireflective (high-transmissive) el ...
Thermally detected optical absorption (TDOA) and photoluminescence experiments are carried out on In0.16Ga0.84N/GaN multi-quantum wells (MQWs) grown by molecular beam epitaxy on (0001) sapphire substrates. A model proposed to adjust the TDOA line shape, al ...
GaInN/GaN quantum dots have been grown by molecular beam epitaxy on sapphire substrates. By changing the size and composition of the dots, the emission energy can be tuned over the entire visible spectrum. We present time-resolved photoluminescence obtaine ...
InGaN/GaN quantum wells (QWs) were grown by molecular-beam epitaxy on c-plane sapphire substrates. The growth of InGaN is carried out at 550 degrees C with a large V/III ratio to counteract the low efficiency of NH3 at that temperature and to promote the t ...
It is shown that the coexistence of toroidally nonlocalized ideal-hydromagnetic ballooning instabilities, with a quasidiscrete spectrum, and toroidally localized ballooning instabilities with a broad continuous spectrum, as predicted by Dewar and Glasser [ ...
A new series of iridium(III) mixed ligand complexes TBA[Ir(ppy)2(CN)2] (1), TBA[Ir(ppy)2(NCS)2] (2), TBA[Ir(ppy)2(NCO)2] (3), and [Ir(ppy)2(acac) (4) (ppy = 2-phenylpyridine; acac ...
The biomedical use of an optical fiber-based spectro- temporal fluorometer that can endoscopically record the fluorescence decay of an entire spectrum without scanning is presented. The detector consists of a streak camera coupled to a spectrograph. A mode ...
