Femtosecond carrier dynamics of Inx Ga1-x N thin films grown on GaN (0001): Effect of carrier-defect scattering
(2007)Ultrafast carrier dynamics in ultrathin Inx Ga1-x N ternary alloys were investigated in detail, using femtosecond transient differential optical absorption measurements. Measurements were performed with probing wavelengths ...

Superimposed gratings WDM on Ge-doped silica on silicon planar waveguide
(1996)Wavelength-division multiplexed (WDM) devices are becoming increasingly important for fiber-optics communication and sensing systems. Large-channel fanout, low loss, and compatibility with fiber connection, laser sources ...

Ultrafast carrier dynamics on conjugated poly(3-hexylthiophene)/[6,6]- phenyl C61 -butyric acid methyl ester composites
(2007)The authors have studied ultrafast carrier dynamics on poly(3- hexylthiophene)/[6,6]- phenyl C61 -butyric acid methyl ester (PCBM) composites up to 50% PCBM concentration. They have resolved the exciton intraband relaxation ...
