Thickness dependence of properties of excimer laser crystallized nano-polycrystalline silicon

Excimer laser crystallization is used to produce layered nanocrystalline silicon from hydrogenated amorphous silicon, using a partial melting process. Three types of hydrogenated amorphous silicon samples, 100, 300, and 500 nm thick, were laser treated in order to investigate the changes to the structural, optical, and electrical properties as a function of amorphous silicon thickness with exci...

Demonstration of directly modulated silicon Raman laser.

The first Raman laser with intra-cavity electronic switching is demonstrated. Digital control of intra-cavity gain is attained by using a diode gain cavity. In contrast to traditional Raman lasers, the Raman laser reported here is made from pure silicon and can be directly modulated to transmit data. Room temperature operation with 2.5W peak laser output power is demonstrated.

Optical field enhancement factor of Silicon and indium phosphide nano-cavities

Nano cavities based on silicon and indium phosphide materials have been comparedin this study, considering field intensity enhancement factor. The results of FDTD based simulations declare that the Si nano-cavity improves confined optical field about 7.7 times higher than the InP based nano-cavity. The introduced dielectric nano-cavities support resonance wavelength at about λ=1.55 μm.

Laser-Induced Chemical Vapour Deposition of Silicon Carbonitride

Laser-induced Chemical Vapour Deposition of silicon carbonitride coatings and powders has been investigated using hexamethyldisilazane (HMDS) and ammonia as reactants. An industrial CW CO2-laser in parallel configuration has been used to heat up the reactant gases. HMDS dissociates in the laser beam and reactive radicals are formed which increase rapidly in molecular weight by an addition mecha...

Hydrogen sensing by localized surface plasmon resonance in colloidal solutions of Au-WO3-Pd

Nowadays, hydrogen has attracted significant attention as a next generation clean energy source. Hydrogen is highly flammable, so detection of hydrogen gas is required. Gold nanoparticle based localized surface plasmon resonance (LSPR) is an advanced and powerful sensing technique, which is well known for its high sensitivity to surrounding refractive index change in the local environment. We p...
