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 ...

Femtosecond laser inscription of Bragg and complex gratings in coated and encapsulated silica and low-loss polymer optical fibers
(SPIE, 2015)The development of wavelength filters, such as Bragg and superstructure gratings in glass and polymer optical fibers, using a femtosecond laser is reported. By using a femtosecond laser operating in the green, which offers ...

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 ...

Ultrafast carrier relaxation in inn nanowires grown by reactive vapor transport
(2009)We have studied femtosecond carrier dynamics in InN nanowires grown by reactive vapor transport. Transient differential absorption measurements have been employed to investigate the relaxation dynamics of photogenerated ...
