We have studied the optical and magnetic properties of ytterbium implanted Gan epilayer grown on (0001) sapphire by metalorganic chemical vapor by deposition (MOCVD). Samples were implanted at room temperature with Yb ions at dose 4 1015 cm-2 and energy of 150 keV. The implanted samples were annealed at 1000 C in n2 at atmospheric pressure to recover implantation damages. The photoluminescence (PL), PL excitation (PLE), and PL kinetics have been studied with continuous and pulse photo-excitations in 360-1100 nm spectral range at different temperatures. The characteristic Yb3+ ion emission spectra were observed in the spectral range between 970-1050 nm. Theoretical fittings of the experimental PL temperature and PL kinetics data suggest that Yb3+ ions are involved in at least two major luminescence centers. The PLE spectra indicate that excitation of the Yb3+ ion occurs via electron-hole pair generation and complex processes. Magnetization versus magnetic field curves shows an enhancement of magnetic order for Yb-implanted samples in 5 K to 300 K temperature range. The Yb-implanted Gan sample showing weak ferromagnetic behavior was compared with the ferromagnetic in situ doped GaYbn material.

Modelling overall transmitted efficiency at 1550 nm for polymer grating Silicon-on-insulator structure with defect

引用

Frontiers of Optoelectronics 2013年第2期6卷 153-159页

The overall transmitted efficiency at 1550 nm for nylon-Teflon/Teflon-nylon （n-T/T-n） grating Silicon- on-insulator （SOI） structure with defect in even and odd position was investigated in this paper. Different types of losses, such as absorption, reflection and diffraction, were considered to find out the overall transmitted efficiency. The absorption loss of both nylon-Teflon （n-T） and Teflon-nylon （T-n） structure is zero at the wavelength of 1550 nm. reflectance of these structures was analyzed by using plane wave expansion （PWE） method. Simulation result showed that reflectance as well as transmittance was varied linearly with respect to defect at odd and even positions. Simulation is also done for the diffraction efficiency at 1550nm with respect to detuning from Bragg＇s angle, which was ranged from -0.4 rad to ＋ 0.4 rad. Finally, it was found that overall transmitted efficiency increased as even defect position varied from 2nd to 10th for both n-T/T-n grating SOI structure. Similarly, the overall transmitted efficiency decreased as odd defect position changed from 3rd to l lth for both n-T/T-n grating SOI structure.
