Optical Absorption Enhancement in Freestanding GaAs Thin Film Nanopyramid Arrays
Optical Absorption GaAs Thin Film Nanopyramid Arrays
2015/8/7
Although III–V compound semiconductor multi-junction cells show the highest effi ciency among all types of solar cells, their cost is quite high due to expensive substrates, long epitaxial growt...
Oxygen and Nitrogen Co-Doped GeSbTe Thin Films for Phase-Change Optical Recording
GeSbTe recording layer oxygen and nitrogen doping optical constants microstructure crystallization temperatures phase-change optical disks
2011/11/28
Nitrogen and oxygen co-doped GeSbTe films for phase-change optical recording are investigated. It is found that optical properties of amorphous and crystalline state are similar to that of GeSbTe, cry...

Complete Temporal Optical Fourier Transformations Dark Parabolic Pulses
2015/7/15
A study of the dynamics of temporal optical Fourier transforms is presented in the interest of improving transform quality. Experimental verification of how a complete Fourier transform can be obtaine...
Optical Deposition of Carbon Nanotubes around Tapered Fibers
Optical Deposition Carbon Nanotubes Tapered Fibers
2015/8/4
We propose and demonstrate carbon nanotube deposition around tapered fibers induced by propagating light through the fibers. A passively mode-locked fiber laser was realized using the fiber.
A Filtered Optical Frequency Comb Generator as a Stable and Tunable Short Pulse Source
Filtered Optical Frequency Comb Generator Tunable Short Pulse Source
2015/7/31
Phase characteristics of pulses from an optical frequency comb generator are studied. Simple filtering is shown suitable for generating stable high quality short pulses of an adjustable pulse width.
