Passive mode-locking in semiconductor lasers with saturable absorbers bandgap shifted through quantum well intermixing [PDF]

open access: yes, 2014
Passive mode-locking in semiconductor lasers in a Fabry–Perot configuration with a bandgap blueshift applied to the saturable absorber (SA) section has been experimentally characterized.

New design of electrostatic mirror actuators for application in high-precision interferometry [PDF]

open access: yes, 2015
We describe a new geometry for electrostatic actuators to be used in sensitive laser interferometers, suited for prototype and table top experiments related to gravitational wave detection with mirrors of 100 g or less.

High-extinction-ratio TE/TM selective Bragg grating filters on silicon-on-insulator [PDF]

open access: yes, 2016
We report on the design and fabrication of TE and TM polarization selective Bragg grating filters in the form of sinusoidal perturbations on the waveguide sidewall and etched holes on the top of the waveguide, respectively.

Hilbert Expansion from the Boltzmann equation to relativistic Fluids [PDF]

open access: yes, 2010
We study the local-in-time hydrodynamic limit of the relativistic Boltzmann equation using a Hilbert expansion. More specifically, we prove the existence of local solutions to the relativistic Boltzmann equation that are nearby the local relativistic ...

Influence of vitamin B12 and light on the formation of chlorosomes in green- and brown-colored Chlorobium species [PDF]

open access: yes, 1993
The specific Bchl a and c content of the vitamin B12-dependent Chlorobium limicola strain 1230 decreased strongly under vitamin B12 limitation. In comparison to a regularly grown culture (20 g vitamin B12/l) the specific Bchl c content of a B12-limited ...

The Vlasov-Poisson-Landau System in $\R^3_x$

open access: yes, 2012
For the Landau-Poisson system with Coulomb interaction in $\R^3_x$, we prove the global existence, uniqueness, and large time convergence rates to the Maxwellian equilibrium for solutions which start out sufficiently close.Comment: 50 ...
